What is a good LRV for walls?

There is no single right number. Light-to-mid neutrals in roughly the 50–70 range are a common whole-house choice, and dim rooms often benefit from higher values. Test a sample in your own light.

Is a higher LRV always brighter?

A higher LRV reflects more light, so it reads lighter. But in a dim room any color looks darker than its chip, and undertone affects whether a light color feels fresh or dingy.

Does LRV tell me if a color is warm or cool?

No. LRV only describes lightness. Undertone has to be judged by comparing samples side by side.

What is LRV (light reflectance value)?

Short answer: LRV (light reflectance value) is a 0–100 score for how much visible light a color reflects: near 0 is black, near 100 is white. Higher LRV colors make a room feel lighter. LRV says nothing about undertone, so always pair it with a physical sample.

What the number means

LRV measures the share of visible light a surface reflects. Real paints never reach the theoretical ends of the scale. Whites sit at the top, deep charcoals and blacks at the bottom, and most popular wall neutrals somewhere in the middle.

Rule-of-thumb bands

LRV	Reads as	Typical use
70+	Whites and off-whites	Ceilings, trim, dim rooms
50–70	Light to mid neutrals	Whole-house walls
30–50	Mid-tones	Bright rooms, accent walls, cabinetry
10–30	Dark	Moody rooms, doors, exteriors
Under 10	Near black	Doors, dramatic accents

These bands are our editorial rule of thumb, not an industry standard.

Where LRV is formally used

Accessibility guidance uses LRV to judge visual contrast. The British Standard BS 8300:2018 treats contrast as adequate when the LRVs of the two surfaces differ by at least 30 points. That's why it matters for things like doors against walls or step edges.

How to use it at home

Dim room? Step up in LRV. See how to read LRV for dark rooms.
Very sunny room? A slightly lower-LRV off-white can feel less glaring than a stark white.
Walls vs trim: a big LRV gap reads crisp, a small gap reads soft and blended.
Two similar chips: the higher-LRV one will read lighter on the wall.

Where it misleads

Two colors with identical LRV can look completely different because of hue and undertone (see warm vs cool undertones). Many LRVs you find online are estimates computed from screen colors rather than measured values. Treat manufacturer-published or measured numbers as more trustworthy.

Test it on your wall first

Peel-and-stick samples are made with real paint and move from wall to wall without brushes or patches.
