Fiddlesticks and flapdoodle.

Yesterday, I selected the hair by group, and used the materials feature to colour it red. This only worked partially, and I'm not sure why.

Today, I created my first near normal head of hair, meticulously went through the process of selecting each group and colouring it red, only to end up with a full head of BLONDE hair?!?!

If anyone can offer me some guidance with regards to hair colouring I would be grateful.

Thank you.
