Currently if someone wants to find an image with only blue hues, or find an image that contains blue and one other colour, they can't find all of them as there's both blue_and_white and black_and_blue. Whereas if they were swapped around, then users could just search blue_and_*

So these would need swapping/aliasing to *_and_black:
black_and_grey
black_and_red
black_and_blue
black_and_brown
black_and_green
black_and_pink
black_and_yellow
black_and_orange
black_and_purple

Then probably aliasing these to match the more standard colours:
black_and_gold -> black_and_yellow
black_and_tan -> black_and_brown
black_and_lavender -> black_and_purple
