So I slept on it and then came back to the teal with fresh eyes and love it. Maybe not an entire room of it (especially one this size) but enough to paint one wall. Or two. (Is it weird to paint only two walls a color, or is that ok? If so, do you paint the connecting corner pair of walls, or the opposing pair?) Then the others I'll do a much softer blue or grey. It's either that or chevron stripes. Or tiny polka dots.
