I have a problem i'm embarrassed to ask as I've probably hit something stupid..... In photoshop, whenever I pick a colour with the eye dropper, it keeps reverting back to grey. I'll double click the foreground/background swatches button and it doesn't matter what colour I choose, it keeps going back to grey. I've tried resetting the tools, shutting it down and re-opening with no luck. Feeling incredibly frustrated and stupid, please help!
