Should I choose a warm or cool white?

Match the fixed finishes and light in the room. Warm whites suit warm woods and creamy stone; cool whites suit cool stone, chrome and crisp modern spaces; neutral whites are the most flexible.

Why does my white paint look yellow?

Usually a warm undertone combined with warm bulbs or warm reflected light from floors or furniture. Cooler bulbs or a more neutral white can fix it.

Why does my white look gray?

Dim or indirect light lowers how bright any color appears. A white that is slightly warmer can look cleaner in shady rooms.

How to choose a white paint

Short answer: Pick a white by its undertone first (warm, cool or neutral), matched to the fixed things in the room like floors, counters and trim. Then check its brightness (LRV) against your light, and test two or three finalists side by side on the wall. A white that looks perfect on a chip can read yellow, gray or stark in your room.

1. Start with what stays

Look at the elements you're not changing: flooring, countertops, tile, trim and big furniture. Creamy stone and warm wood usually pair with warmer whites; cool marble, chrome and gray tile usually pair with cooler or neutral whites.

2. Read the undertone

Every white leans somewhere. Hold candidates against a sheet of plain printer paper: the comparison makes their lean (yellow, pink, green, blue, gray) jump out. Learn more in warm vs cool undertones.

3. Match brightness to light

The brightest, highest-LRV whites can feel glaring in a very sunny room and flat or gray in a dim one. A slightly softer off-white often looks more "white" in a dim room than a stark one. See what LRV means.

4. Decide your trim strategy

Same white on walls and trim: calm and seamless; vary only the sheen.
Brighter trim: crisp edges; keep the undertones compatible.
Ceiling: see how to choose a ceiling color.

5. Test big, in your light

Whites are especially sensitive to bulb color and surrounding colors. Follow our sample testing method and see our guide to ordering samples.
