The saying "the more the merrier" doesn't always apply when it comes to colour.

There's no official limit of how many colours are allowed in one room. But the saying "the more the merrier" doesn't always apply when it comes to colour. If you want to know whether or not you have too much colour mixing in one room? The room will feel the opposite of peaceful — sometimes it even feels like it's closing in. Aim for one or two primary colours and a handful of secondary, accent colours. Keep in mind where the colours are located in the room and spread them around evenly so the eye is carried through a room.
