A glaze is colored glass laid over a dry painting. Light passes through the thin film, bounces off the layer underneath and comes back tinted, which is why glazed shadows look deep and glazed skin seems to glow. That only works if the paint is genuinely transparent. Load an opaque color into a glaze and you get a cloudy veil instead of stained glass. So the best oil paints for glazing are transparent, finely ground, high-tint pigments, used with a medium that helps the film level and dry.
This guide explains which pigments glaze well and which do not, then compares seven products sold on Amazon: single transparent artist colors, a transparent white for milky glazes, an alkyd glazing medium, a set of transparent dry pigments for advanced painters, and two oil paint sets with the label details to check before using them for glazing.
Quick answer: Start with one or two genuinely transparent colors and a glazing medium. Winsor & Newton Winton Burnt Sienna is labeled transparent with an ASTM I lightfastness rating and AA permanence, and it is the classic warm glaze. Sennelier Transparent Brown adds a deep, warm transparent earth for shadows. Mix either with Gamblin Galkyd Painting Medium, an alkyd medium designed to level, add gloss and speed drying between layers.

How We Chose
These picks are based on Amazon listing details and specifications checked in October 2026, how suitable each product is for transparent layering according to its label information and well-established pigment properties, and how widely each product is reviewed by Amazon buyers. We have not glazed with these specific products.
- Transparency: labeled transparent or made from pigments known to be transparent.
- Lightfastness: thin glazes have little pigment, so permanence matters.
- Fine grind and tinting strength: to stain evenly in a thin film.
- Medium compatibility: a medium that levels and dries reliably.
- Label clarity: sets that do not state transparency per color are ranked lower.
Which Oil Colors Glaze Well
Transparency is a property of the pigment, not the brand. These pigments are widely known as transparent or semi-transparent and are the usual glazing choices:
- Earths: burnt sienna, transparent oxide red, transparent oxide brown and transparent oxide yellow. Warm, lightfast and versatile.
- Reds and pinks: quinacridone rose, quinacridone magenta, alizarin crimson and perylene reds.
- Blues: ultramarine (semi-transparent), phthalo blue (very strong) and Prussian blue.
- Greens: phthalo green and viridian.
- Violets: dioxazine purple and ultramarine violet.
Pigments that usually work poorly as glazes because they are opaque include titanium white, the cadmiums, cerulean blue, chromium oxide green and yellow ochre. They can still be used in a glaze for a deliberate veiling effect, but expect a cloudier result.
Check the label. Good artist and student lines print a transparency symbol, often an open square for transparent and a filled square for opaque, along with the pigment code. If a set does not show this, test each color by painting a thin stripe over a black line on white paper. A transparent color lets the line show clearly.
Best Oil Paints for Glazing Reviewed
1. Winsor & Newton Winton Oil Color, Burnt Sienna, 37 ml — Best for affordable transparent glazing
Burnt sienna is one of the most useful glazing colors there is, and the Winton tube is clearly labeled. The listing gives Series 1, color code 074, transparency rated T (transparent), permanence AA (extremely permanent) and lightfastness ASTM I (excellent).
A thin burnt sienna glaze warms a cool underpainting, deepens wood and skin shadows, and unifies a painting that feels disjointed. It is also a classic toning color, so the tube will not go to waste.
Best suited for: Beginners learning to glaze, and any painter who wants a dependable warm glaze.
Key features:
- 37 ml tube
- Transparent (T) per label
- Permanence AA
- Lightfastness ASTM I
Pros:
- Clearly labeled properties
- Very affordable
- Versatile warm earth
Cons and limitations:
- Student-grade line
- Single color
- Earth colors can look dull if overused
Buying consideration: Use a little paint and a lot of medium for the first glazes. A glaze that is too strong is harder to fix than one that is too weak.
2. Sennelier Artists’ Oil Color, Transparent Brown, 40 ml — Best for artist-grade transparent earth
Sennelier’s artist line is made with pure first-press safflower oil, and the listing notes pigments ground slowly to an extra-fine consistency. Transparent Brown, a Series 3 color, gives a deep, warm transparent dark for shadow glazes and old-master-style backgrounds.
Extra-fine grinding matters in glazes because the paint is spread so thin that any coarse particles show as texture or streaks.
Best suited for: Painters who want a rich transparent dark for shadows and classical effects.
Key features:
- 40 ml artist oil
- Safflower oil binder
- Extra-fine grind
- Series 3
Pros:
- Artist grade
- Deep, warm transparent color
- Fine for thin films
Cons and limitations:
- Higher cost per tube
- Safflower oil dries more slowly than linseed
- Single color
Buying consideration: Because safflower oil dries slowly, give each glaze extra drying time, or use an alkyd medium to speed things up.
3. Gamblin Galkyd Painting Medium, 4 oz — Best for a glazing medium
A glaze is mostly medium with a little paint. Galkyd is Gamblin’s alkyd resin medium, and the listing details note a gloss finish. Alkyd mediums are widely used for glazing because they help paint level into a smooth film, increase gloss and transparency, and speed drying so you can apply the next layer sooner.
Faster drying is the practical win. Linseed-oil glazes can take days to dry; an alkyd medium can shorten that considerably, which keeps a multi-layer painting moving.
Best suited for: Anyone glazing who wants smooth, glossy films and faster drying between layers.
Key features:
- 4 oz alkyd painting medium
- Gloss finish
- Gamblin brand
Pros:
- Levels and adds gloss
- Faster drying between glazes
- Pairs with Gamsol solvent
Cons and limitations:
- Becomes tacky quickly once on the palette
- Can be too glossy for some styles
- Alkyd odor
Buying consideration: Put out only a small amount at a time. Alkyd medium starts to set on the palette, which is good on the canvas but wasteful in the cup.
4. Gamblin 1980 Oil Colors, Transparent White, 37 ml — Best for milky, atmospheric glazes
Most whites are highly opaque, which makes them poor glaze colors. A transparent white is different: it lightens and softens without covering what is underneath. Gamblin 1980 is the brand’s more affordable line.
A thin layer of transparent white can push a background back into atmospheric haze, soften a too-harsh edge, or create a pearly veil over skin. Add a touch of a color to make tinted mists.
Best suited for: Atmospheric effects, softening areas, and lightening glazes without opacity.
Key features:
- 37 ml oil color
- Transparent white
- Gamblin 1980 line
Pros:
- Lightens without hiding layers
- Useful for haze and veils
- Affordable
Cons and limitations:
- Specialized use
- Listing gives few technical details
- Not a mixing white for opaque passages
Buying consideration: Use it sparingly. Several thin veils look better than one heavy one.
5. C.A.S. AlkydPro Transparent Glazing Pigment Set — Best for mixing your own glazes
This is a set of 10 dry pigments in 2 fl oz jars, not tube paint. The listing describes a transparent glazing palette including transparent oxide yellow, orange, red and brown, perylene and ultramarine violet colors, and two pearlescent pigments (gold light and silver white). All 10 are described as transparent or semi-transparent, at artist-grade concentration with superior lightfastness.
Dry pigments are ground into oil or medium by the painter. That gives full control over transparency and consistency, but it requires care and safe handling of fine powders.
Best suited for: Experienced painters who want custom transparent glazes, including interference shimmer effects.
Key features:
- 10 dry pigments, 2 fl oz each
- Transparent iron oxides and perylene
- Two pearlescent pigments
- Usable with oil, alkyd, acrylic and watercolor binders
Pros:
- Wide transparent palette
- Full control over paint
- Unique pearlescent effects
Cons and limitations:
- Requires grinding into a binder
- Dust safety precautions needed
- Premium price tier
Buying consideration: Wear a mask and gloves when handling dry pigment, and mix small batches with a muller or palette knife on glass.
6. Paul Rubens Oil Paint, 20 Colors x 50 ml — Best for underpainting plus glazing
Glazing needs a solid underpainting, and underpaintings use a lot of paint. Paul Rubens’ set provides 20 colors in 50 ml tubes. The listing describes high pigmentation, good covering power and tinting strength, refined linseed oil and excellent lightfastness.
The listing does not mark transparency per color, so test each tube with the black-line method before using it for glazing. Expect earths and blues to be most useful, and opaque colors to be better for underpainting.
Best suited for: Painters who want large tubes for underpaintings and are willing to test which colors glaze.
Key features:
- 20 colors, 50 ml each
- Refined linseed oil
- High pigmentation per listing
Pros:
- Large tubes
- Good for underpainting
- Wide palette
Cons and limitations:
- Transparency not labeled per color
- Covering power suits opaque work more than glazes
Buying consideration: Make a transparency chart on the first day. It turns an unknown set into a known palette.
7. MyArtscape Oil Paint Set, 24 x 21 ml — Best for learning which colors glaze
MyArtscape’s set includes 24 colors in 21 ml tubes, including titanium white, lemon yellow, cadmium red, phthalo green, ultramarine blue, burnt umber and black. The listing describes lightfast, high-sheen, creamy paint.
Phthalo green and ultramarine blue are both useful glazing colors, and a 24-color set is an inexpensive way to compare transparent and opaque behavior side by side.
Best suited for: Budget learners who want to experiment with glazing across many colors.
Key features:
- 24 colors, 21 ml each
- Includes phthalo green and ultramarine blue
- Lightfast per listing
Pros:
- Budget-friendly
- Larger tubes than 12 ml sets
- Wide palette
Cons and limitations:
- Transparency not labeled per color
- Mix of opaque and transparent colors
Buying consideration: Separate the colors into transparent and opaque groups after testing, and keep the transparent group for glazes.
Buying Guide: How to Choose Oil Paints for Glazing
Transparency rating
Look for a transparency symbol on the tube or a pigment known to be transparent. This is the single most important factor.
Lightfastness
Thin glazes contain little pigment, so fading shows quickly. Choose ASTM I or II or equivalent ratings.
Tinting strength
High-tint pigments such as phthalos stain strongly in thin films; use tiny amounts. Earths are gentler and easier to control.
Glazing medium
Alkyd mediums level and dry faster. Oil-based mediums dry more slowly and give a softer gloss. Follow fat over lean as layers build.
Underpainting palette
Glazes need a value-correct, dry underpainting. Opaque, larger tubes are economical for that stage.
Drying time
Each glaze must be dry before the next. Plan your schedule and choose mediums accordingly.
Three Glazes Worth Learning First
The warm unifying glaze
A very thin burnt sienna or transparent brown glaze over an entire dry painting pulls disparate colors into one warm family. It is the quickest way to fix a painting that feels like separate parts.
The shadow deepener
Glaze ultramarine plus a touch of transparent brown into shadow areas. Shadows become darker and cooler without losing the drawing underneath, which is far more convincing than repainting them with opaque dark paint.
The color shift
Glaze crimson over a dry gray-green underpainting of a red apple, or phthalo blue over a gray sky. The underpainting does the value work and the glaze adds pure, luminous color, a two-step approach that produces richer results than mixing the final color directly.
A Simple Glazing Sequence
- Paint a value-correct underpainting and let it dry completely.
- Mix a glaze: a small amount of transparent color with plenty of medium.
- Brush it thinly over the area. Use a soft, wide brush to avoid streaks.
- Wipe back with a lint-free rag where you want highlights to stay light.
- Let it dry, then evaluate and add another glaze if needed.
- Finish with highlights in thicker opaque paint, then varnish once fully cured.
For the full technique, see our oil painting glazing technique guide. When the painting is completely dry, our guide on how to varnish an oil painting correctly explains timing and application, and how to varnish and protect your oil paintings covers long-term care.
Common Mistakes to Avoid
- Glazing with opaque colors. The result is cloudy, not luminous.
- Glazing over wet paint. It muddies both layers.
- Too much paint in the glaze. Start weak and build.
- Breaking fat over lean. Glaze layers should be fatter than those beneath.
- Using coarse brushes. They leave streaks in thin films.
- Skipping drying time. Each layer must dry.
FAQs
What oil colors are best for glazing?
Transparent pigments such as burnt sienna, transparent oxides, quinacridones, alizarin crimson, ultramarine, phthalo blue and green, and viridian.
Can I glaze with any oil paint?
You can, but opaque colors produce a cloudy veil. Transparent colors produce the luminous effect glazing is known for.
What medium should I use for oil glazing?
An alkyd medium such as Galkyd levels, adds gloss and speeds drying. Oil-based glazing mediums dry more slowly.
How long should a glaze dry before the next layer?
Until it is fully touch-dry. Alkyd mediums can shorten this to about a day for thin layers; oil mediums can take longer.
How do I know if a paint is transparent?
Check the transparency symbol on the tube or test a thin stripe over a black line on white paper.
Do I need artist grade paint for glazing?
Not necessarily, but clear transparency and lightfastness labels matter. Student lines with good labeling can work well.
Final Recommendation
Start with Winton Burnt Sienna and Galkyd to learn glazing affordably. Add Sennelier Transparent Brown for deep artist-grade shadows and Gamblin 1980 Transparent White for haze and veils. Experienced painters can explore the C.A.S. AlkydPro transparent pigment set. Use Paul Rubens or MyArtscape sets for underpaintings and testing, after checking which of their colors are transparent.
