Alex, Layers>Foci>Edit Foci Colors is one option for generating colors, but it is indeed tedious if you have more than a few to assign.
A better way is to capitalize on a color-creation option that John recently implemented in Window -> Caret Command Executor. Select COLOR FILE CREATE MISSING COLORS, then follow the instructions in the Command Description box. This tells you how to enter input and output color file names and specify the data file name and format (foci or foci projection in your case). Once the quasi-random colors are assigned based on the foci names, you may edit selected ones at your leisure if you don't like the particular assignments. One other point - you should always be able to see the foci as little red dots even if there are no foci colors assigned. If you saw absolutely nothing, and if it is an unprojected foci file, you need to view the fiducial surface.
