The impulse of coloring everything is strong. The idea of having everything dark in a game of horror is only natural. But your colors are only interesting and useful if they don’t hide content with their flair. In other words, a rule of thumb: if it is hard to read your colored content than it is to read it in black and white, you’re doing something wrong. Some will type ‘color’ and ‘look’ and ‘color’ again to read what you wrote in black and white – others won’t bother reading it all.
