Two of America’s most respected artist oil paint makers sit only a short drive apart in Oregon, yet they made very different choices about what goes into a tube. M. Graham builds its colors on walnut oil; Gamblin builds most of its range on linseed oil and wraps it in a well-known system of solvents and mediums. Comparing M. Graham vs Gamblin oil paints comes down to binder, handling, drying, palette range and how you like to work, so that is how this guide is organized.
Quick answer: M. Graham oils use walnut oil, which gives a buttery, slightly looser paint that is popular with painters who want to work without solvents and who like slow drying. Gamblin Artist’s Grade oils mostly use linseed oil, feel stiffer and more consistent from tube to tube, dry somewhat faster, and sit inside a complete system of mediums and odorless solvent. Neither is universally better; choose M. Graham for solvent-free, slow, buttery handling and Gamblin for structure, a broad range and a matched medium system.
The Two Companies at a Glance
Both are American, family-founded and focused on professional paint. Both publish clear pigment information on their labels, which lets you compare colors by pigment code rather than by marketing name. The differences that matter are in formulation philosophy.
M. Graham’s approach is simple: pure pigment, walnut oil, and as little else as possible. The brand leans heavily into solvent-free painting, offering walnut oil and a walnut-based alkyd medium so you can thin and speed up your paint without turpentine or mineral spirits.
Gamblin’s approach is systematic. Its artist colors are part of a broader lineup that includes Gamsol odorless mineral spirits, alkyd mediums, cold wax, varnishes and a student line. If you like having a known medium for every job, Gamblin’s ecosystem is a major draw. We compare Gamblin against another premium maker in depth in our Holbein and Gamblin oil paint comparison, which is useful context if you are building a palette from several brands.

Prices vary widely by series, pigment and retailer, so compare the specific colors you need rather than relying on brand averages.
Binder: Walnut Oil vs Linseed Oil
The binder decides a lot more than many painters expect. It shapes how the paint feels on the knife, how it levels, how fast it dries and how the film ages.
Walnut oil in M. Graham
Walnut oil is a traditional painting oil with a long history. It tends to yellow less than linseed oil, which is one reason painters like it for whites and pale mixtures. It also dries more slowly and produces a film often described as slightly less tough than linseed. In practice, M. Graham colors stay workable longer on the palette, which helps alla prima painters who return to a mix after lunch.
Linseed oil in Gamblin
Linseed oil is the classic oil painting binder. It dries relatively quickly by oxidation and forms a strong, flexible film. Its slight tendency to yellow, especially in the dark, is usually minor in mixtures but more visible in pure whites. Gamblin’s handling reflects this binder: paint holds a stroke, takes a knife edge well and builds texture predictably.
Both brands make colors that are archival when used with sound technique. The binder choice is about handling and drying more than permanence.
Handling and Consistency on the Palette
Squeeze out the same pigment from each brand and the difference is usually visible within seconds. M. Graham colors often slump into a soft pile; Gamblin colors tend to sit up with peaks.
- Brushwork: M. Graham’s softness makes long, flowing strokes easy and blends wet-into-wet smoothly. Gamblin’s firmer body preserves brush marks and edges.
- Impasto: Gamblin generally holds texture better straight from the tube. With M. Graham, painters who want thick ridges often add a little cold wax or a stiff gel.
- Glazing: M. Graham thins readily with walnut oil or its alkyd medium. Gamblin thins well with its own mediums and gives fine control over transparency.
- Consistency between colors: Gamblin works hard to make different pigments feel similar. M. Graham varies more, since it tends to avoid stabilizers that equalize body.
Drying Time and Layering
Drying depends on pigment as much as brand. Earths and lead-based colors dry quickly; cadmiums and some organics dry slowly. Still, the binder shifts the baseline.
M. Graham’s walnut base usually gives a little more open time. That is helpful for wet-into-wet and frustrating if you want to glaze the next day. Adding M. Graham’s walnut alkyd medium speeds things up noticeably.
Gamblin colors typically touch-dry sooner in thin layers. With an alkyd medium in the mix, many painters can layer within a day in normal room conditions.
When mixing brands in one painting, follow fat over lean as usual. Walnut and linseed oil are compatible, but put slower-drying, fatter layers on top, not underneath.
Color Range and Pigment Choices
M. Graham offers a tighter, practical palette built around reliable single pigments. That suits painters who mix most colors from a limited set and appreciate fewer decisions.
Gamblin’s range is larger and includes historically inspired and specialty colors, along with convenient mixtures. If you need a specific hue for a commission or prefer premixed greys and earth variations, Gamblin is more likely to have it.
Whatever the brand, compare by pigment index codes. A phthalo blue (PB15) from either maker will behave similarly in mixing strength, even if the binder changes the feel.
Solvent-Free Painting
This is where M. Graham has a clear identity. Clean brushes in walnut oil, thin with walnut oil, speed drying with walnut alkyd medium, and you can paint a complete picture without any solvent in the room. That appeals to painters with small studios, kids at home or sensitivity to fumes.
Gamblin supports solvent-free work too, with a solvent-free gel and fluid mediums, but much of its system is designed around its odorless mineral spirits, which is a low-odor, highly refined solvent. Low odor still means vapors, so good ventilation matters with any solvent.
Which Brand Fits Your Painting Style?
| Painting style or need | Better fit | Why |
|---|---|---|
| Solvent-free studio | M. Graham | Entire workflow built on walnut oil |
| Alla prima, slow sessions | M. Graham | Longer open time on the palette |
| Knife painting and impasto | Gamblin | Firmer body holds texture |
| Layered glazing over days | Gamblin | Faster drying and a wide medium choice |
| Large or unusual palette | Gamblin | Broader color range |
| Limited palette, budget conscious | Either; compare per-color price | Both offer strong single-pigment staples |
Common Mistakes When Switching Between Them
- Over-thinning M. Graham. It is already soft. Adding too much oil can make films slow, weak and prone to wrinkling.
- Expecting the same drying schedule. A layer that is dry overnight with Gamblin may still be tacky with M. Graham.
- Not kneading the tube. If oil pools at the top of a walnut-based tube, roll and squeeze it before opening, or blot excess oil on a paper towel.
- Ignoring fat over lean. Mixing binders is fine, but a slow walnut layer under a quicker linseed layer can cause cracking.
- Judging by color names. The same name can hide different pigments; always read the code.
Can You Mix M. Graham and Gamblin on One Palette?
Yes. Both are oil paints with compatible drying oils, and many painters combine brands to get the best color from each. Keep a few rules in mind: be aware that walnut-based mixes may slow overall drying, keep medium use consistent within a layer, and test a small mixture first if you are combining alkyd mediums from one brand with paint from the other.
A sensible hybrid approach is to use the brand you prefer for whites and the pigments you use most, then fill gaps with single colors from the other line.
How the Whites Compare
White is the color most painters use in the largest quantity, so it deserves its own look. It also shows binder differences more clearly than any other tube.
M. Graham titanium white in walnut oil is soft and tends to stay cleaner and cooler over time because of walnut oil’s lower yellowing tendency. Its looser body makes it easy to mix into other colors but less ideal if you want crisp impasto highlights straight from the tube.
Gamblin offers several whites with different handling, including options with stiffer body for texture and faster-drying formulations. Read each label, because some whites use a different oil than the rest of the range to reduce yellowing. That variety gives you more control over how highlights behave.
A practical test is to paint swatches of each white side by side, thin and thick, and leave one card in a dark drawer for a few months. Any yellowing differences become easy to see, and you learn more from your own swatch than from any spec sheet.
How to Test Both Brands Before Committing
- Buy the same three pigments from each brand. A good set is a titanium white, an ultramarine blue (PB29) and a burnt sienna (PBr7). These cover tinting strength, transparency and drying range.
- Make a drawdown. Spread each color thinly with a palette knife next to its rival. Compare masstone, undertone and tinting strength by mixing equal amounts with white.
- Paint a small study with each. Use the same subject, surface and medium. Note how long each stays workable and how edges behave.
- Check drying. Touch-test thin swatches every 12 hours and record when each feels dry.
- Decide by workflow, not reputation. The brand that suits how you paint is the right one for you.
Storage and Shelf Life
Walnut oil paints can separate more in long storage. Store M. Graham tubes cap-down or flat, and massage them before use. Gamblin tubes are less prone to this but still benefit from cool, stable storage. Always clean tube threads before recapping to avoid stuck caps, which is the most common way any paint tube gets ruined.
FAQs
Is M. Graham oil paint professional quality?
Yes. M. Graham Artists’ Oil is marketed and widely used as professional-grade paint with high pigment content and single-pigment formulas for most colors.
Why is my M. Graham paint oily when I open the tube?
Walnut oil can separate from pigment over time, especially without added stabilizers. Knead the tube before opening and blot any pooled oil on a paper towel.
Does Gamblin oil paint dry faster than M. Graham?
Generally, yes, because linseed oil dries faster than walnut oil. Pigment, film thickness, temperature and mediums all change the actual drying time.
Which is better for beginners, M. Graham or Gamblin?
Gamblin’s consistent body and matched mediums make learning predictable. M. Graham suits beginners who specifically want to avoid solvents from day one.
Can I use Gamsol with M. Graham paint?
Yes. Odorless mineral spirits work with any oil paint. Many M. Graham users simply choose walnut oil for cleanup to stay solvent-free.
Do walnut oil paints yellow less?
Walnut oil is generally considered less yellowing than linseed oil, which is why some painters prefer it for whites and pale tones.
Final Thoughts
Choose M. Graham if you want buttery paint, slow drying and an easy route to solvent-free painting. Choose Gamblin if you want firm, consistent paint, faster layering and a complete medium system. Many painters end up owning both.
