More lighting colours

With the new addition of green copper lanterns and the updating visuals for lighting I thought it would be cool if more lighting colour options could be added in a similar way. E.g. In a desert or ocean update they could include patches of dried ancient oceans with salt flats including new blocks like sylvite which would be not only be cool for building as another pink/coral block, but, as a form of potassium chloride to create purple lanterns - more options with the dynamic lighting.
