changing colors of model

ruggb

My models (loaded or sliced) r a deep dark blueon one computer and yellow on another. I can't see any detail with the blue. I tried chg colors under Config/preferences but that doesn't chg the model color. What is wrong? How do I chg the model color?

Repetier

It uses the extruder colors from Printer Settings-> Extruders. If you change the color there it changes.
