Why Doesn't Light Paint Cover the Number? 3 Tricks for an Even Result

Why doesn't light paint cover the number? 3 tricks for a smooth finish

Have you ever opened a new Paint by Numbers (Paint by Numbers) set, excited about the bright yellow or soft pink, but disappointed with the first brushstroke? The paint spreads beautifully, but the black number still stubbornly shows through.

This is one of the most common challenges in the hobby. The good news is that it’s not a faulty paint, but a law of physics that can be easily bypassed.

Why is light acrylic paint translucent?

Before you blame the Paint by Numbers set for poor quality, it's good to understand a bit about colour theory. Certain pigments – especially yellows and oranges – are naturally more translucent than dark shades.

Trick 1: "White Savior" (The easiest way)

💡 Hobbyist Pro Tip:

Remove the number from view before painting.
Use a regular white marker (e.g., Posca) or a white colored pencil. Cover the numbers on the canvas where light paint will be applied. When the base is white, even yellow paint will appear bright!

This is definitely the fastest way to achieve a neat result without thick layers of paint.

Trick 2: Layering is patience

If you don't have a white marker, take advantage of the quick drying of acrylic paint. Don’t try to cover the number with one thick layer.

Do this:

  • Paint a thin layer of light colour. The number will still show through – that’s okay.
  • Let the layer dry completely (about 10–15 minutes).
  • Paint a second layer over it with a light touch.

Trick 3: Thick drop (Impasto style)

If you want texture, you can try the dotting technique. Take more paint on the tip of the brush and "dab" it over the number. A thick layer of paint prevents light from passing through.

Summary: Relax and enjoy the process

Translucent colours are part of the painting hobby. Try a white marker or calm layering, and you’ll notice the difference immediately.
