Changing Colour of an Object With a GUI.Button Back to Original

Hi,

I've imported a level from Sketchup, and what I want, is when a GUI.Button I've created is pressed, all objects I've specified (by declaring them as Renderer variables) to change to the color yellow. Then upon clicking the button again, back to their original color at the start.

The code I have currently changes them to yellow wonderfully, but to white, when clicked again. It happens within the DoSomething function, near the bottom of the code block. All my variables are specific objects in which I assign their mesh renderer to. I've tried, everything from using their exact (R,G,B) colors in place of white, to trying to setup an original color variable. But I can't seem to figure it out. Any help would be much appreciated.

Thanks K.
