A collage project
In your sketchbook or on a piece of paper or card – choose a single colour (example red) and make up a page consisting of this colour. It could be a collage of paper, wrappers, magazine pictures or scraps of fabric plus coloured pencils and pens. Cut and tear into pieces. How many varieties of red, yellow, blue or green can you see and find? They could be arranged in patterns or laid out at random or even layered but all in shades of one colour.
Alternatively do a drawing or a still life of items that are one colour (ie a study in blue for example might include a number of blue objects clustered together).
Think about how different colours make you feel. Do you have a favourite colour and what does it say about you.
