🔢 Color by Number for Kids - Free Online and Printable

What are colour by number activities?

A colour by number picture is a simple line drawing divided into small areas. Every area holds a number, and a little key at the side tells your child which colour belongs to each number: 1 might be red, 2 blue, 3 yellow, and so on. The child reads the number, finds it in the key, and fills the space with that colour. Nothing is hidden or tricky — the fun is in watching the finished picture appear bit by bit.

On this page you will find 7 free colour by number activities with friendly subjects that young children love: a butterfly, a fish, a rainbow, a flower and an elephant. Spellings for both color and colour are included, so you can pick the version that matches the English your school uses.

Skills children learn

These activities look like quiet play, but a lot of learning is happening at the same time.

• Number recognition: children see and read numerals again and again in a natural way.
• Colour names: matching a number to red, green, blue or orange builds vocabulary.
• Matching and sorting: checking the key and finding the right colour is early logical thinking.
• Fine motor control: colouring inside small areas strengthens the fingers for writing.
• Focus and patience: finishing a picture teaches children to stay with a task until it is done.
• Confidence: there is one clear, correct result, so children feel proud of the finished artwork.

How to play online and how to print

Every activity works in two ways. To play online, open an activity on a phone, tablet or computer, tap a colour from the palette, then tap the areas marked with that number. Mistakes are easy to fix — just tap again with the right colour. There is nothing to download and no login needed.

To use it as a printable worksheet, open the activity and choose the print option. Print on plain A4 paper and give your child crayons, colour pencils or sketch pens. Printed sheets are ideal for classrooms, long journeys, rainy afternoons and screen-free time. Teachers can print one copy per child, or print a few and keep them in a folder for early finishers.

Ideas by age

Ages 2–3: toddlers are still learning numerals, so sit beside them and read the numbers aloud. Let them colour freely if they wish — at this age the goal is holding a crayon and enjoying colour, not accuracy. The online version is often easier for little hands because one tap fills a whole area.

Ages 4–5: this is the sweet spot. Preschool and kindergarten children can read the key themselves and work area by area. Ask them to say the number and the colour out loud: "Three is yellow." Finish one picture in a sitting, then display it on the fridge or class board.

Ages 6–8: older children can work independently and faster. Challenge them to finish without looking back at the key after a while, or to count how many areas use each colour. Afterwards, invite them to draw their own picture, split it into parts, add numbers and make a colour by number puzzle for a friend.

Tips for parents and teachers

• Keep the colour key visible at all times; do not expect children to remember it.
• Start with pictures that have fewer, larger areas, then move to more detailed ones.
• Praise the effort and the neat edges, not just the finished picture.
• Use the activity as a calm-down task after a busy lesson or before bedtime.
• For group work, print one sheet per child but share crayons so children practise taking turns.
• Talk about the subject afterwards: where butterflies live, what elephants eat, how rainbows form.
