How to use these reviews
Start with the LRV filter. It tells you how light a color will read on the wall before undertone even comes into it: whites sit above 75, most popular greiges and light grays between 55 and 75. Then open two or three colors with similar LRVs and compare their undertones, because at the same lightness the undertone is what you will notice.
When two colors look almost the same on screen, check the comparison pages. Each one puts the numbers side by side and explains which room and lighting suits which color.
