i am trying to mix a blue to match the coffee can in the image. While it looks like I am close, I can't quite get it. Further, the bright light from the side raises the value to a point where the ultramarine Geneva paint can't get there (or I can't get it there). Using white gives it a milky look, and yellow ( it is a warm blue) beyond a very limited amount, of course turns it green. Have I reached the limit of this color and need to go elsewhere to match this color? Thanks for your help. The pic is desaturated compared to the actual.
