Images are made up of different coloured 'pixels'. This image below has 8 rows and 8 columns, meaning it has 8x8=64 pixels total. Hex codes are a way of representing colours. They are made up of a hash symbol (#) followed by six numbers 0-9 and/or letters A-F. Enter up to 64 hex codes (e.g. #ff0000#00ff00#0000ff...) to make your own image!
