North vs south facing rooms
Short answer: In the Northern Hemisphere, north-facing rooms get indirect, cooler-looking light that can make colors look grayer and darker, while south-facing rooms get strong, warmer light for much of the day. East rooms are brightest in the morning and west rooms in the late afternoon. Choose and test colors for the light the room actually gets when you use it.
By direction (Northern Hemisphere)
| Window faces | Light | What tends to happen | Often works |
|---|---|---|---|
| North | Indirect, even, cool-looking | Colors read grayer and darker; cool colors can feel chilly | Warmer undertones, higher LRV |
| South | Bright, warm, changes through the day | Colors look lighter and warmer; very warm colors can turn intense | Most colors; cool or muted tones balance it |
| East | Bright morning, dimmer afternoon | Big shift through the day | Test in the evening as well as the morning |
| West | Soft morning, strong warm evening | Evening glow can push colors orange | Test in late afternoon |
In the Southern Hemisphere, swap north and south.
Don't forget the bulbs
At night, your bulbs take over. Warm bulbs push colors yellow; cool ones push them blue. See how lighting changes paint color.
Other factors
Trees, neighboring buildings, overhangs and the colors of floors and furniture all bounce or block light. A north room with a big window can be brighter than a south room under a porch, so judge the room you have.

FAQ
- What color is best for a north-facing room?
- Colors with a warm undertone and a relatively high LRV usually hold up best, because north light tends to make colors look cooler and darker. Always test first.
- Do cool colors work in south-facing rooms?
- Often yes. Strong warm light can balance cool or muted colors, though very icy whites can still look stark at midday.
- Does this apply in the Southern Hemisphere?
- Yes, with north and south swapped: there, south-facing rooms get the indirect light.
