Computers store images broken up in to small pieces called pixels. It’s like a mosaic.
Each pixel is a different colour. Each colour has its own number. A number is stored for each pixel saying what colour that pixel is. To display a picture the computer has to do a colour-by-number puzzle!
Colour in the squares below using the colours from the colour key to get a picture of some Christmas Food.
