Ok so I got bored this morning and was messing around with your paint scheme hope you dont mind. But this is what I came up with.
one question are you set on using those colors? Red yellow and blue? reason I ask is there primary colors and even though they go together well I think changing the yellow to a lighter blue would be easier on the eye.
let me know what you think
EDIT* just noticed the color on my picture is a bit off. guess it must have changed when I converted it from PDF to JPG. but you get the idea.
