Only shades of gray showing up

While trying to change colors on my color palette, I noticed that all of my colors are showing up as various shades of gray. No matter how many times I choose a different color, it shows up as gray. Sure that works great if I just want to work in black,white and all of the grays in between, but I need a little color in my latest project.

Any help would be greatly appreciated.

Right off the top of my head, two things....

Either you have IMAGE > MODE set to grayscale (set it to RGB)
OR
You have the "channels" pallet active with a single channel selected.

Check that and I'll think a little harder.. :D

Neither of those worked, so I went to drastic measures, uninstall and then reinstall. Now my color palette is working fine. Much thanks for the advice though.

Now if I can just try to remember what caused the problem so it doesn't happen again... lol
