There is no single rule that fits every canvas, but there is a useful beginner principle: when two colours sit beside each other, painting the lighter colour first is often easier.
Quick answer: use light-before-dark as a colour rule, and top-to-bottom as a hand-position rule. You can combine both rather than choosing only one system.
Why paint lighter colours first?
Darker acrylic colours generally cover pale colours more easily than pale colours cover dark ones. If a tiny amount of a pale colour crosses a boundary, the neighbouring darker colour can often cover it cleanly later.
The reverse is less forgiving. A strong dark blue, brown or black mark underneath a pale yellow or cream may need additional coats.
Does that mean you should paint every light colour before every dark colour?
No. That would often mean jumping around the entire canvas, which can become inefficient.
A practical approach is to work within one area of the painting and use the light-before-dark principle where neighbouring sections make it useful.
Should you paint from top to bottom?
Top-to-bottom is helpful because it reduces the chance of resting your hand or wrist on freshly painted sections.
Right-handed painters may find it comfortable to move roughly from top-left toward bottom-right. Left-handed painters may prefer top-right toward bottom-left.
Should you paint one colour at a time?
Working one colour at a time reduces brush washing and keeps your paint routine simple. It works especially well when the same colour appears in several nearby parts of the canvas.
You do not need to paint every occurrence of that number across the whole picture before moving on. Use the method that keeps the project organised without making you stretch across wet areas.
A simple beginner order
- Choose one area of the canvas to work in.
- Begin near the top if you tend to rest your hand on the surface.
- Within neighbouring sections, paint lighter colours before much darker colours when practical.
- Let wet sections dry before painting a sharply contrasting colour directly beside them.
- Use another thin coat later if a printed number still shows through a pale section.
What about white and very pale colours?
Pale colours sometimes need more than one thin coat to hide the printed number completely. Let the first coat dry before deciding whether another is necessary.
Do not compensate by loading the brush with a very thick layer. Thick acrylic can create ridges and make the surface less even.
What if you accidentally paint outside the line?
Let the mistake dry. If the neighbouring colour is darker, you may be able to cover the small overlap when you paint that section. For a larger mistake, allow it to dry fully before correcting rather than rubbing wet colours together.
Does the order affect the final painting dramatically?
Usually not. Paint order is mostly about making the process cleaner and easier. A careful painter can get a good result using several different methods.
The best system is the one that helps you avoid smudging, keeps paint pots from drying out and lets you work steadily.
