What Order Should You Paint by Numbers? Light or Dark Colours First?
Summary
You should paint light colours before dark colours in paint by numbers. This guide explains exactly why, walks through the correct four-step painting order, and covers the most common sequencing mistakes that cause muddy edges and colour bleed.
One of the most common questions beginners ask when they open their first kit is where to actually begin. The canvas has dozens of numbered sections, and it is not immediately obvious whether you should work from left to right, top to bottom, or in colour order. The answer matters more than most people realise, and getting it right from the start will make a visible difference to your finished painting.
This guide answers the question definitively and explains the reasoning behind each step, so you understand not just what to do, but why it works. If you are still choosing your first kit, our beginner-friendly collection is the best place to start.
Paint by numbers canvases contain both light and dark numbered sections. Knowing which to paint first makes a significant difference to your finished result.
Should You Paint Light or Dark Colours First in Paint by Numbers?
Paint light colours before dark colours. Acrylic paint is opaque, which means dark colours will cover light ones cleanly if you accidentally paint outside the lines. The reverse is not true. A dark colour that bleeds into a light section is extremely difficult to correct, because light paint cannot fully cover dark paint in a single coat.
This single rule prevents the majority of mistakes that beginners make. When you work light to dark, any small errors at the boundary between two sections are automatically corrected as you go. The dark colour simply covers the stray light paint when you fill that section later. To understand more about the acrylic paint that comes in your kit and why it behaves this way, read our guide on what paint is used in paint by numbers.
The Correct Four-Step Painting Order
Beyond the light-before-dark principle, there is a complete painting sequence that produces the cleanest results on any canvas.
The four-step painting order that produces the cleanest, most professional results on any paint by numbers canvas.
Paint the Background First
Start with the large background sections that make up the sky, water, grass, or any wide open area of your canvas. These sections are usually painted in lighter, softer colours, and cover the most surface area. Getting them done first means you never have to work carefully around a finished foreground element, and any loose brushwork at the edges will be covered by the foreground colours you paint next.
Work Through the Light Colours
Once the background is dry, move through the lightest colours in your palette. These are typically your creams, pale yellows, soft pinks, light blues, and whites. Paint all sections that share each light colour before moving to the next shade. Working colour by colour, rather than section by section, reduces the number of times you need to rinse your brush, and minimises the risk of cross-contamination between pots.
Move to the Mid-Tones, Then Dark Colours
Progress gradually from lighter mid-tones through to the darkest colours in your palette. The darkest shades, your deep blacks, navies, and forest greens, should always be the last colours you apply across the main canvas. By this point, all adjacent light sections will already be dry, and any boundary work between a dark and a light section will be clean and precise.
Add the Fine Details Last
The finest details, including eye catchlights, whisker strands, thin outlines, and highlight dots, should always be the very last things you paint. These require maximum precision, and painting them onto an already-completed surrounding section gives you the clearest possible visual reference for placement. For these sections, a dedicated detail brush from our accessories collection will give you far more control than your standard kit brushes.
Should You Paint by Numbers in Numerical Order?
No. Numerical order, starting at number 1 and working through to the highest number, has no artistic logic behind it. The numbers are simply labels that match paint pots to canvas sections. They carry no information about which colour should be applied first.
Following numerical order will cause you to jump constantly between light and dark colours, skip around the canvas randomly, and rinse your brush far more often than necessary. It is one of the most common beginner mistakes, and it produces noticeably messier results than following the light-to-dark colour sequence.
Starting with light colours first means any accidental overlap can be covered cleanly by the darker colours that follow.
Before you open a single pot, lay all your paint pots out in order of lightness, from your palest shade to your darkest. This takes about two minutes, and gives you a clear visual roadmap for the entire session. You will paint left to right across that line of pots, rather than searching for the right colour each time. It also makes it much easier to spot if any pots are missing, or have the wrong numbers.
Why Do Light Colours Need to Go First? The Science Explained
The reason light-before-dark works comes down to the chemistry of acrylic paint. Acrylics are pigment-based, and highly opaque when applied correctly. A single coat of a dark colour contains enough pigment density to completely obscure the lighter colour beneath it. The reverse is not true. Light colours contain less pigment and more white, which means they are naturally more transparent, and cannot fully block out a darker shade beneath them, even with two or three coats.
This is the same principle that artists use when working with acrylics on a blank canvas. You always build from light to dark, because you can always go darker, but you cannot reliably go lighter without completely repainting a section from scratch.
Dark colours applied after light ones stay clean and crisp. The opacity of acrylic paint means dark shades cover any light colour that has strayed across the boundary.
Does It Matter Where on the Canvas You Start?
Yes, but less than the colour order. The practical rule is to start in the top left corner of your canvas and work towards the bottom right if you are right-handed, or top right to bottom left if you are left-handed. This means your painting hand never rests on, or drags across, a section you have already completed, which prevents smudging wet paint.
Working in sections, rather than jumping across the canvas, also helps you maintain consistent colour results. If you load your brush with a colour and paint all the sections using that colour before rinsing, you get a consistent tone throughout. Jumping back to the same colour after rinsing can sometimes produce a very slightly different shade, if the pot has started to thicken.

Frequently Asked Questions
Should you paint light or dark colours first in paint by numbers?
Always paint light colours before dark colours. Acrylic paint is opaque, so dark colours will cover any light paint that strays over a boundary line. Light colours cannot cover dark ones cleanly, making errors much harder to fix if you work dark to light.
Should you do paint by numbers in order?
Not in numerical order. Instead, follow a light-to-dark colour sequence, and start with the background sections first. Numerical order has no artistic basis, and will produce messier results than painting by colour family.
Where do you start with paint by numbers?
Start with the largest background sections first, then work through your lightest colours towards your darkest. Within that sequence, start at the top of your canvas and work downwards, to avoid dragging your hand through wet paint.
What order do you do paint by numbers?
Background first, light colours second, mid-tones third, dark colours fourth, and fine details last. This four-step sequence produces the cleanest results on any kit, regardless of the design or colour count.
Do you start paint by numbers with number 1?
No. The numbers are simply labels matching paint pots to canvas sections. They carry no information about the painting sequence. Following numerical order will cause you to jump randomly between light and dark colours, which produces noticeably messier results.
