That is impossible, color-blind people wont see them as perceptually uniform since the area with the color they can't see gets a lot darker. For example I can't see red text on a certain kinds of black background, as in I don't even recognize that there are letters there. I remember being on a presentation where the author apparently liked to play with colors, and several of the screens were just blank to me I didn't even know that I there were letters there I couldn't see.
