Selecting a paint color for your space can be extremely overwhelming, particularly considering paint colors look different in every room. So before you even begin browsing colors, let’s talk about room light and orientation—this is truly the surest way to get started on the right foot.
The direction your room faces plays a huge role in how paint colors appear, and understanding this upfront will help uncover which colors you should even be looking at in the first place.
To determine your room’s direction, find the largest windows in the space and note which way they face. If the majority of the windows are on the north side, you have a north-facing room.
Here’s a breakdown of each directional space and what it means for paint selection.
North-Facing Rooms
Rooms facing north receive the least amount of natural light, which can make paint selection a bit more challenging. Because the light in these spaces is naturally very cool, you’ll want to select paint colors with warm undertones to offset that coolness.
This could be a white or even a darker, moodier color—just make sure it leans warm. Without that balance, paint colors in north-facing rooms can easily feel flat or dull.
South-Facing Rooms
Since north-facing rooms receive the least amount of light… you guessed it—south-facing rooms receive the most.
This abundance of natural light actually makes paint selection a bit easier, as most colors tend to work well in these spaces. That said, it doesn’t mean you can throw just any paint color on the wall.
You’ll want to avoid overly warm paint colors, as they can feel much too bold at certain points in the day. Neutral-toned and cooler-toned paints tend to work best here.
Bottom line: whichever paint color you choose for a south-facing room, it’s always going to look warmer once it’s on the wall.
East- and West-Facing Rooms
An east-facing room receives warmer light in the morning and cooler light toward the end of the day. A west-facing room is the opposite—cooler light in the morning and warmer light later in the day.
Unlike north- and south-facing rooms, east- and west-facing spaces experience shifting light throughout the day. Because of this, there are a few different approaches you can take when selecting paint.
When Do You Use the Room Most?
If you don’t use the room consistently throughout the day, let usage guide your paint choice.
For example, if your east-facing room is a primary bedroom that’s mostly used in the evening, selecting a warmer paint color can help balance the cooler afternoon light.
Go Neutral
If the space is used fairly evenly throughout the day, neutral paint colors are a great option. They create balance and flexibility, and they won’t pigeon-hole you into a specific design direction as the light changes.
Mix Cool + Warm Tones
If usage of the space is more sporadic—or if you’re like me and enjoy mixing things—lean into it.
Choose a paint color you love that works well in the room, then mix cool and warm tones through furniture, décor, and accessories. This layering of tones helps create balance and harmony, even as the light shifts throughout the day.
Understanding LRV (Light Reflectance Value)
We’ve talked about warmer and cooler paint colors and how to approach selection based on room orientation—but what’s the best way to actually narrow things down?
Look for the LRV, or Light Reflectance Value.
Every paint color has an LRV number on a scale from 0 to 100.
-
0 represents absolute black, which absorbs all light.
-
100 represents pure white, which reflects all light.
The higher the number, the more light the paint color reflects.
How LRV Applies to Room Direction
Let’s apply this to what we covered above.
Because north-facing rooms receive the least amount of light, paint colors with a higher LRV are often a better place to start, as they’ll help reflect more available light back into the space.
That said, this doesn’t mean you can’t go darker in a north-facing room. If the space is primarily used at night—say, for watching movies—it might make sense to lean into a darker paint color to create a cozy, moody vibe.
Think of LRV as a helpful litmus test for where to begin—not a hard rule.
