Is there a way to toggle the display of colors/appearances in a solidworks part? There are toolbar buttons for toggling display of things like wireframe, solid, shaded, zebra lines etc., but none for turning the display of colors on and off.

Something like this would be very useful because many times I add color to the model to make it look more realistic, but then it's more difficult to work with the part, especially if the color is black - it's hard to see anything.
