Bring a bright rainbow to life with this free colour by number activity for kids. Every part of the picture has a small number in it, and each number stands for one colour. Children match the number to the colour key, then fill the arcs, the sun, the fluffy clouds, the grassy hill and the little flowers.

It is a calm, happy activity for preschool and early primary children. Use it at home on a rainy day, in a quiet corner of the classroom, or as a printable worksheet for colouring practice and number recognition.

How to play

Look at the colour key and read each number with your child, saying the colour name out loud.
Find a number inside the picture, then pick the crayon or pencil that matches that number.
Colour that area neatly, staying inside the lines, and tick off each number as you finish it.
Keep going until every area is filled, then hold up your finished rainbow and name all the colours.

This rainbow colouring page quietly builds many early skills at once. Your child practises number recognition from 1 to 10, matches each number to the right colour, and learns the names of colours like purple, orange and sky blue. Staying inside the lines strengthens pencil grip and fine motor control, which later helps with neat handwriting. Working through the key from top to bottom also teaches patience, careful looking and following instructions step by step. Sit nearby, ask "which number comes next?", and let your child choose the order of colouring to keep the activity relaxed and enjoyable.

Frequently asked questions

What age is this rainbow colour by number best for?

It works well for children aged four to six. Younger children may need help reading the key, while older kids can finish on their own. The areas are large and simple, so little hands can colour them without getting tired.

Can I print this worksheet for free?

Yes, the rainbow colour by number page is completely free to print at home or in school. Use plain A4 paper for crayons and pencils, or slightly thicker paper if your child likes to press hard or use sketch pens.

What if my child uses the wrong colour?

That is perfectly fine. The aim is enjoyment and practice, not perfection. Gently point back to the colour key and let your child decide whether to change it. Many children enjoy making their own rainbow version afterwards.

Which colours do we need for this page?

You need red, orange, yellow, green, blue, purple, sky blue, white or light grey, pink and light green. A basic ten-shade crayon or pencil set covers almost all of them, and close shades work just as well.
