North-facing rooms:
Light in these rooms is cool and bluish. Bolder colors show up better than muted colors, while lighter colors may appear subdued. Strong colors work well in these spaces.
South-facing rooms:
These rooms receive a lot of high-in-the-sky light, which brings out the best in both cool and warm colors. Dark colors will appear brighter, while lighter colors will seem to glow.
East-facing rooms:
East light is warm and yellowy before noon, and then turns bluer later in the day. Reds, oranges, and yellows work particularly well in these rooms.
