To make a custom shader you need other shaders, I'm not talking about adding something like what warftame has, I'm going for an extention of the system we have now we're you can move the colors from shader to shader and even take those shaders apart and move the colors around... Right now with 1 shader their is only 1 application I want the take 1 shaders and have 1,000 applications, it's up to how creative you are... Imagine if you could also mix colors like mixing gold with blue would give you blue tinted gold.
