Start with the dark colors and work toward the light ones. That is the short answer for a paint by numbers kit, and the rest of this article explains why, how much it actually matters, and what ordering decisions make more difference than this one does.
mixing colors in a numbered kit covers the times you do need to mix, which are fewer than most people assume.
If you are painting outside a kit, what you actually need to start is a shopping list rather than an inventory of an art shop.
Why dark to light works
Paint by numbers kits use acrylic, and acrylic is opaque. That single fact drives the whole answer.
- Dark paint hides the printed numbers in one coat. Light colors, especially yellows and creams, often need two before the printing stops showing through. Getting the darks down first means most of the canvas is covered early.
- Mistakes correct in the right direction. If a light color strays over the line into a dark section, the dark covers it easily when you get there. Going the other way — dark straying into a pale section — takes several coats to bury.
- The composition appears sooner. The darks are usually the background and the shadow shapes. Laying them in first gives you the structure of the image within the first session, which makes the rest much easier to judge.
- Your eye calibrates better. Once the darkest value is on the canvas, every lighter color you add can be judged against it. Starting with the lights gives you nothing to measure against.
How much does it really matter?
Honestly, less than most articles suggest. With opaque acrylic on a printed canvas you are filling in defined shapes, not blending values, so a kit painted light-to-dark will finish perfectly well. Anyone telling you a painting will be ruined by the wrong order is overstating it.
Dark to light saves you some second coats and some tidying up. That is the real benefit, and it is worth having, but it is a preference rather than a rule.
The ordering choices that matter more
Three habits make a bigger difference to the finished canvas than light-versus-dark does.
One color at a time
Paint every section marked with the same number before you move on. It saves washing the brush between every section, it keeps you from losing track of which number you were on, and it uses less paint. This is the single most useful habit in paint by numbers.
Large areas first, small details last
Big sections go quickly and give you the shape of the picture early. The fine detail is slower and more demanding, and it is much easier when the rest is already down. Leaving the smallest sections until the end also means less chance of smudging them with your hand.
Top to bottom, and across if you are right-handed
Work down the canvas so your hand rests on finished, dry areas rather than wet ones. If you are right-handed, working left to right helps for the same reason. Resting your hand on a spare sheet of paper is worth doing either way.
Tips for applying the color
- Use enough paint to cover, but not so much that it sits proud of the canvas. Two thin coats beat one thick one.
- Expect the pale colors to need a second coat over the printed numbers. Let the first dry completely before adding it.
- Clean the brush properly between colors. Even a little of the previous color will dull the next one.
- Let adjacent sections dry before painting the one beside them, or the edges will pull into each other.
- Close each pot as soon as you have finished with it. Acrylic dries in an open pot faster than you would think.
- Do not rush. These are designed to be done over several evenings, not in one sitting.
If a pot has already thickened, our guide to reviving dried paint covers the fix, and there is a matched replacement set for every design if one has gone past saving.
What about oil and watercolor?
Worth answering briefly, because the advice you find online is usually about these rather than about kits.
Oil is traditionally worked dark to light, partly for the same reasons as above and partly because of the fat-over-lean rule — leaner, faster-drying paint underneath, oilier paint on top, or the surface cracks as it cures.
Watercolor is the opposite: light to dark, always. Watercolor is transparent, so a light color will not show over a dark one, and you cannot paint white back in — the white is the paper, and any area you want to stay white has to be planned before you start.
Neither applies to a standard paint by numbers kit, which is acrylic. Acrylic is the most forgiving of the three: it is opaque enough to work in any order, dries fast enough to layer within an hour, and can be thinned with water to behave more like watercolor if you want it to. There is more on that in our comparison of acrylic and watercolor paint by numbers.
Wrap up
Start dark, finish light. You will cover the numbers in fewer coats and your mistakes will be easier to fix. But the habits that matter more are painting one color at a time, doing the large areas before the small ones, and giving each section time to dry.
