I am trying to edit an image (imported png saved as xcf), mode is already RGB but still the whole Colours menu is greyed out and none of the usual colour tools work (colorise, HUE-mode layers, etc). All layers remain stubbornly black and white. The colours menu is completely greyed out, mode is already RBG, file is xcf. Help!
