Troubles with color palette

In C11 (which I love BTW) I have some kind of strange glitch. Previously I set up the default palette to match my orchestral templates, that all works well. However Today I decided to add a red color for the stereo out but. I can seem to find a way to add an additional color. I have tried the Project Colors setup on the Project drop down (all three tabs) and the little palette on the tool bar and teh little icon on the tool bar in the project window. No “Options” button as described in the manual here and no alternatives
