I have never gotten along very well with colour pencil. Even now I am not able to beat a 5 yr old on terms of shading and blending colours.
I'm not even comfortable changing B/W into colour. It always ends in tears. Mine.
But I've had a year of my Uni teachers telling me: Have you thought about adding colour? ...just a bit, how about a wash? a pale yellow? You could just try one colour...anything.
So I decided to give colour a try. Especially since my friends bought me expensive colour pencils for my birthday.
