Color picker is all off.

I can't seem to get the color picker in the item editor to select the right color. I use the he color picker to make a robe green, I select the right color and it shows in the swatch, I save the item and it turns out orange or yellow. I even tried pasting in hex codes, and it is still doing it. Sometimes it'll pick a totally random color. I tried to make a robe blue and it turned it green, then purple. I think I got that one to be the right color after several tries, but other items it's just a hit or miss kind of thing, and most of the time it's a miss.
Am I missing something here? Is there a better system?
