Mermaid Magic

Light enough to feel airy, colored enough that it still counts as a decision rather than a default. 7562, from Vista Paint.

66.0 on the light-reflectance scale puts it in the middle third, which is the part of the scale with the fewest surprises. A chroma of 15.1 is enough to register as a real color choice, without the intensity that would force the rest of a room to match it.

This is a color worth testing in the specific room it is going in - cool colors shift more than warm ones do between north and south walls. Works well in rooms that need brightness but where a plain white feels too cold or too clinical. Vista Paint Light Lavendar makes a good second wall color here - different enough to read as a real choice, close enough to still feel related (about 19 points apart in light reflectance).

By the numbers, Valspar Mint Gala (6001-7B) and this color are indistinguishable - delta-E 0.61, well under what the eye can separate. Matte holds the color truest; a subtle sheen will lift it half a shade under lamps.

It is lighter than 69 percent of the Vista Paint range. This is a crowded part of the scale - 861 colors measure within a point of 66.0 - so most brands will have something close. Vista Paint lists it in the K codes, alongside 1,318 other colors.
