So went with the black paper. I forgot that I get more of a painted look with black paper, not sure why I don't use it more, I like it.
A lot of people say that when you use yellow coloured pencils on black, you run the risk of it looking green, but I've never had that happen. Maybe because I never use just straight yellow on the black paper? I put down a light layer of yellow first and then if its an eye like this, a light layer of brown.If its flowers, I try to mix a bit of red into the yellow, or actually green to make a blue flower.
