What Is a Colour By Code Worksheet?
Haven't heard the term colour by code? That's OK! Maybe you've heard of colour by numbers or colouring by maths? Or maybe you call them mystery picture worksheets?
These fun worksheets allow students to pull out their crayons or coloured pencils to colour a picture based on a predetermined colour key or code, where each colour corresponds to a specific number or symbol. The goal is to match the numbers or symbols on the picture with the corresponding colours to reveal a mystery picture.
Colour by code refers to not just colour by numbers but also colour by parts of speech, synonyms, addition and other educational concepts!

History of Colour by Numbers
Ever wonder how colouring by numbers became so popular?
The exact history of these sheets is hard to track down, but as far back as the early 20th century, people were 'painting by number' as a recreational activity. Then an activity mainly for adults, it involved painting pre-drawn canvases with numbered sections that corresponded to specific paint colours.
In the 1950s, an American artist called Dan Robbins developed a commercial version of the concept called 'Paint by Numbers' that helped the idea go mainstream and give life to what we now call colour by numbers in schools! His kits included pre-printed canvases, numbered paints and brushes, and his idea was soon adapted to make colouring books for kids.
In the versions for kids, numbers or symbols were added to line drawings instead of canvases, and young children could easily colour within the lines using crayons or coloured pencils!
