Green Lime

Strong enough that it sets the palette for the room, not the other way around. 0771 in the Vista Paint range.

Chroma 33.9 is high enough that the color will bounce onto light surfaces, so expect it everywhere, not only on the wall. In a room with plenty of natural light, this can cover more wall area than it could in a dim one, where the same color reads heavier.

Warm bulbs will soften it; daylight bulbs push it further cool. LRV 66.0 tells you how much light comes back, which matters less here than how much color comes with it.

If the room already has purples in the floor, a rug, or the furniture, this color will fight it rather than sit well beside it - the two sit at opposite ends of the color spectrum, which is exactly why they clash instead of blend.

Next to it, white trim reads brighter and cooler than it does anywhere else in the house - the gap in light reflectance is what does that, not the trim paint itself.

Behr Igloo pairs well as a second surface - close enough in feel to belong in the same room, far enough in lightness to read as two distinct walls (about 338 points apart on the reflectance scale). Matte suits a color this strong - a glossier sheen would turn every light source in the room into a visible hotspot on the wall.

Across the other brands, nothing lands within delta-E 2 of this one - there is no easy substitute.

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 C codes, alongside 1,421 other colors.
