Quick answer: The most useful palette preparation tips are to lay colors out in the same order every session, keep white in the largest pile and farthest from the darks, leave the center open for mixing, and match the palette surface to the medium (sealed or glass for oil, damp stay-wet for acrylic, white ceramic or enamel for watercolor). Prepare the palette before the first brushstroke, not during, and clean or cover it at the end of every session so the next one starts in seconds.
A palette prepared with some thought lets you find colors without looking, judge values accurately, and keep paint usable for as long as the session lasts. A palette prepared carelessly produces muddy mixes, wasted paint, and a lot of hunting for the blue you squeezed out ten minutes ago. These palette preparation tips cover the surface, the layout, the quantities, and the care routine, for oil, acrylic, and watercolor, in the studio and on the road.
Step 1: Match the Palette Surface to the Medium
Preparation starts before any paint comes out. Each medium has a surface that works with it and one or two that fight it.
| Medium | Good surfaces | Avoid | Why |
|---|---|---|---|
| Oil | Glass over neutral gray, sealed wood, disposable paper | Raw wood, absorbent paper | Oil soaks into unsealed surfaces and the paint goes dry and chalky |
| Acrylic | Stay-wet tray, glass, smooth white plastic, paper palette | Textured plastic, cardboard | Acrylic bonds to texture and is nearly impossible to remove once cured |
| Watercolor | White ceramic, enamel tin, white plastic with wells | Anything tinted or glossy-dark | Washes must be judged against white to read their true value |
| Gouache | White ceramic or plastic with deep wells | Flat surfaces with no wells | Gouache is re-wettable; wells let you revive it later |
A new wooden palette needs sealing before oil paint touches it. Rub in two or three thin coats of linseed oil over a few days, or apply a coat of shellac or clear varnish, and let it cure fully. Many painters also “tone” a new wooden palette by scrubbing a mid-gray oil mix over it, which cuts the warm wood color that distorts how mixtures look.
If you paint away from home, the surface question has an extra constraint: it has to close. Lidded trays, folding tins, and sealable stay-wet boxes are compared in the guide to travel-friendly palettes, and the preparation steps below apply to all of them.
Step 2: Decide on a Fixed Color Order
The single habit that separates efficient painters from frustrated ones is a consistent layout. When every tube goes in the same place, your hand learns where colors are and you stop breaking concentration to search.
There is no one correct order, but the most common conventions are:
- Spectrum order: White, then yellows, oranges, reds, violets, blues, greens, then earths and black. Mirrors the color wheel, so neighbors on the palette are also neighbors in hue.
- Warm-to-cool: White at one end, then the warm colors, then the cool colors, with earth tones grouped at the opposite end from white.
- Value order: Lightest to darkest. Less common, but useful for tonal painters.
Whichever you choose, place white where it will not be contaminated: at the end of the row, with the largest pile, and never beside the darkest colors. A stray smear of ultramarine in your white is far more damaging than a smear of white in your ultramarine.
Step 3: Squeeze Out Sensible Quantities
Beginners tend to squeeze out either far too little (and spend the session re-squeezing) or far too much (and throw away half of it). A rough guide for a two- to three-hour session on a canvas around 16 x 20 inches:
- White: A pile about the size of a walnut. It goes into nearly every mixture.
- Main colors: Hazelnut-sized piles for the two or three colors dominating the subject.
- Supporting colors: Pea-sized piles. You can always add more.
- Black and strong staining colors (phthalo, dioxazine): Half a pea. They overpower everything.
Squeeze piles along the top and one side of the palette, about an inch apart, leaving the lower center completely clear for mixing. Keep each pile compact and tall rather than spread flat; a tall pile exposes less surface to air and dries slower.
Step 4: Prepare the Mixing Area
The empty center of the palette is where the work happens, and it benefits from a little structure.
- Divide it mentally into zones. Lights toward the white, darks toward the darks, neutrals in between. Mixtures you intend to return to stay put; one-off mixes go at the bottom where they can be scraped away.
- Keep a clean strip. Reserve a few inches of untouched surface for checking a mix against the canvas tone or for testing a tiny sample before committing a large pile.
- Pre-mix the big ones. If the painting has a dominant sky, skin tone, or ground color, mix a generous pile of it before starting and set it beside its parent colors. Running out midway and trying to re-match is a classic time sink.
- Scrape between stages. Clear the mixing area with a palette knife when you move from blocking in to detail. Leftover mud from the first stage contaminates the cleaner color of the second.
Step 5: Medium-Specific Preparation
Oil
Set out a palette cup clipped to the edge with your medium (linseed, a solvent-and-oil mix, or an alkyd) and a second cup with clean solvent if you use one. Tone a glass or wooden palette to a mid-gray if it is not already neutral. A neutral palette surface is especially helpful for judging values in oil, where everything looks darker against a white background and lighter against a dark one.
Acrylic
Acrylic skins over within 10 to 20 minutes in normal room conditions, so preparation is mostly about slowing that down.
- With a stay-wet palette: soak the sponge until saturated, pour off the excess water so it is damp rather than dripping, and lay the membrane paper over it smoothly. Too much water and your paint turns runny; too little and it skins anyway.
- Without one: mist the palette with a spray bottle every few minutes, and keep piles tall. A piece of damp paper towel under a sheet of parchment paper makes an improvised stay-wet surface.
- Add a few drops of retarder to the piles you expect to blend from, not to everything, because retarder weakens the paint film if overused.
Watercolor
Preparing a watercolor palette means filling the wells with tube paint and letting it dry before use, or arranging pans in a consistent order in a tin. Fill wells about three-quarters full, let them set for a day or two with the lid open, and label the underside if the colors are not obvious once dry. Before a session, lay a drop of clean water on each color you plan to use so the surface softens and the brush can lift pigment without scrubbing.
Watercolor palettes also benefit from several separate mixing areas, because a dirty mixing well turns every wash gray. Three or four wells minimum; more for complex work.
Palette Preparation for Travel and Outdoor Painting
Working outside compresses every problem: wind dries paint, light changes, and there is no table. Preparation shifts toward compactness and containment.
- Pre-squeeze at home. Oil painters can lay out a glass or paper palette the night before and seal it in a palette box or wrap it in cling film. Acrylic painters should squeeze on site but can pre-load a stay-wet tray with a damp sponge.
- Limit the colors. Six to eight colors plus white covers almost any landscape. Fewer piles means a smaller palette, fewer tubes in the bag, and more harmonious mixes.
- Use a lid. A closing palette protects wet paint between sessions and keeps grit out. For watercolor, a folding tin with pans is the standard solution. The roundup of compact palettes for painting on the move compares the lidded formats that suit each medium.
- Carry a scraper and a rag. Cleanup in the field is mostly scraping the mixing area back to usable and wiping the knife.
Some painters working on landscape and nature subjects keep a second, dedicated outdoor layout with earth tones and greens weighted heavily, so that the studio palette and the field palette each stay optimized for their own subjects.
Preparing a Limited Palette
A limited palette is a deliberate choice to work from very few colors, often for color harmony or training. Preparation here is about the choice of colors and their arrangement rather than quantity.
| Limited palette | Colors | Good for |
|---|---|---|
| Zorn | Yellow ochre, cadmium red (or vermilion), ivory black, titanium white | Portraits, tonal studies, understanding temperature with almost no blue |
| Split primary | Warm and cool yellow, warm and cool red, warm and cool blue, white | Clean secondaries, general-purpose painting |
| Earth palette | Yellow ochre, burnt sienna, raw umber, ultramarine, white | Underpaintings, classical approaches, muted landscapes |
| Three primary | One yellow, one red, one blue, white | Color mixing practice, sketching, travel |
Lay a limited palette out with white at one end and the colors in the order you will mix them most often. For a Zorn layout, white, ochre, red, black is the usual sequence, so that the flesh mixes (white, ochre, red) are adjacent and black stays isolated. Painters working in traditional academic approaches frequently build a whole method around an earth-based layout; the piece on the best palette for classical art describes those arrangements in more detail.
Preparing a High-Chroma Palette
At the other extreme, painters chasing bright, broken color need more piles and more separation. Impressionist-style work typically uses two of each primary plus a violet, a bright green, and no black. The preparation tips here are:
- Space piles farther apart, since there are more of them and cross-contamination is more visible in high-chroma mixes.
- Keep complementary pairs on opposite sides of the mixing area so a stray smear does not instantly gray a color.
- Pre-mix two or three key tints (a sky blue, a sunlit yellow-green, a shadow violet) in generous quantity.

End-of-Session Routine
How you leave the palette decides how fast the next session starts.
- Scrape the mixing area clean with a palette knife. Wipe the knife on a rag.
- Decide what to save. Oil piles stay workable for several days if covered; a sheet of cling film pressed directly onto them, or a lidded palette box, slows drying. Acrylic piles survive only in a sealed stay-wet tray, and even then for a few days before mold appears. Watercolor dries in its wells and is simply re-wetted next time.
- Clean glass and ceramic with a razor scraper and a damp cloth. Clean plastic by soaking in warm water and peeling.
- Store flat and covered. Dust settling on a wet palette ends up in tomorrow’s paint.
Some oil painters keep the same piles going for a week by moving the palette into a freezer or a sealed box with a few drops of clove oil; both slow oxidation. Neither helps with acrylic, which cures by evaporation rather than oxidation.
Common Palette Preparation Mistakes
- Random layout each session. Costs time every single session and causes accidental mixes.
- White in the middle. It gets contaminated from both sides. Keep it at an end.
- Too many colors out. Twelve piles for a two-color subject invites mud. Set out what the painting needs.
- Dark or wood-colored surface for judging value. Every mix looks lighter than it is. Tone wood to gray, or back glass with gray or white.
- Mixing on top of pure piles. Pull paint from the edge of a pile into the mixing area; never mix inside the pile itself.
- Skipping the scrape. A palette coated in half-dried sludge fights every clean mix you try to make.
FAQs
How should I arrange colors on my palette?
Choose one consistent order, usually spectrum or warm-to-cool, and repeat it every session. Put white at one end in the largest pile, keep darks away from it, and leave the center open for mixing.
How much paint should I put out at the start?
For a two- to three-hour session, a walnut of white, hazelnuts of the two or three main colors, and peas of the rest. Keep piles tall rather than flat so they dry slower.
How do I keep acrylic paint from drying on the palette?
Use a stay-wet palette with a damp sponge and membrane, mist the piles with water every few minutes, keep piles compact, and add a few drops of retarder only to colors you will blend from.
Do I need to seal a wooden palette before using it?
Yes, for oil paint. Rub in several thin coats of linseed oil or apply varnish or shellac, let it cure, and optionally tone it gray. Unsealed wood absorbs the oil from the paint.
What is the best way to prepare a palette for painting outdoors?
Limit yourself to six to eight colors plus white, use a lidded palette or tin, pre-squeeze oils at home if possible, and carry a scraper and rag for in-field cleanup.
Can I leave paint on the palette overnight?
Oil, yes, if covered with cling film or a lid; it stays workable for days. Acrylic only in a sealed stay-wet palette. Watercolor dries in its wells and re-wets without any harm.
Next Step
Preparing a palette well is a five-minute habit that pays back on every brushstroke: a fixed order, sensible quantities, an open mixing area, and a surface suited to your medium. Set it up the same way each time, and the layout becomes invisible, which is exactly what you want.
If your painting happens outside the studio, the lidded, compact formats compared in the guide to the best palette for travel make these preparation tips practical in a backpack as well as on a table.
