Look at my delicious box of Inktense pencils I had for christmas! I love the strong colours but the colours on the ends of the pencils don't correspond to the colour they produce on the paper so there was only one thing to do! This was fun, needed no brain (mine seems to be on pause at the moment) and I now have a useful chart that I can refer to for ever, or until it falls apart or gets tea stains all over it.
Right then, what colours shall I choose for my next picture? Hmmmmmm.
