You are tracing your photocopy using the baking paper - this is outlines only. You can use the window if that is helpful.
Photocopy your tracing 2 times
Have a look at the colour theory info under this and colour one of your photocopies. You need to colour the whole paper - background included. You need to focus on:
blending analogous colours together
placing complementary colours beside each other
Creating a focal point by having a bold colour surrounded by greens - this could be a flower
Your colours do not have to be the same as your photocopy - get creative.
