Key takeaways
- LRV runs from 0 (absorbs all light) to 100 (reflects all light).
- The lighter a colour, the higher its LRV.
- In a dim room, a higher LRV helps keep it bright.
Understanding the scale
A deep black is close to 0 and a very pure white approaches 100. Mid-tones sit in the middle. Manufacturers often print the LRV on the colour chip or in the colour’s details.
Choosing by room
- Dark or north-facing room: aim for a higher LRV to offset the cooler light.
- Very bright room: a darker colour can work without making it gloomy.
- Bright neutrals often sit around 50 to 60 LRV.
What LRV does not tell you
LRV does not describe the shade (yellow, blue, pink) or the effect of the lighting. It does not replace a test on the wall. Finish matters too: a glossier finish reflects more light.
Using it in practice
Compare the LRV of two colours you are torn between. If one is much lower, the room will feel darker with it, especially in the evening.
Frequently asked questions
- Does a high LRV mean a white?
- No. A pale yellow or a light grey can also have a high LRV.
- Where do I find the LRV?
- On the back of the colour chip, in the manufacturer’s colour details, or by asking your painter.
