So i have prepared my line art and now I am ready for color. The problem is when I go to color my palette is nothing but grays. HELP!!!!!!!

There was another post a couple of days ago about this.

You either have and alpha channel or an idividual channel selected or you are in greyscale mode.

Go to your channels pallet and make sure the top most item, which chould say RGB is selected.

:)

thanks that was the problem
