it is your boring grey or black and white for a reason.. colored icons will hog system resources.

I don't see how displaying color can hot a system's resources. The colors are going to be defined by a variable. When you set this variable to say, white or red, it's all the same for the OS - it's just storing a value in memory. Regardless of what the color is, a value must still be stored and read from memory.
