This board is kind of weird, so I'll do my best to explain what my aim is for this place.
Simply start a thread with a color or color scheme that you like, and people can fill it with images that fit that color/color scheme. Or make a game out of it if you want (ex: post a picture who's color relates to the previous image).
It doesn't necessarily have to be colors, "themes" are acceptable as well (ex: cats, tile, technology, retro, etc.).
tl;dr: This place is an OCD circlejerk.
