colours (or colors if you subscribe to the american spelling)
I feel particularly challenging tonight so here is a new challenge for all you challenge freaks.
Choose a base colour (red, green, blue, yellow, white or black – yes I know black technically isn’t a colour) and write a ficlyt that contains just that one colour in different shades. I.e. red can be crimson or burgundy. Extra points if you do not actually name the base colour. Even more points if the story has a twist.
