Slippery Shale

It has just enough yellow-green cast to have a personality, and just little enough to stay out of the way. Slippery Shale is Vista Paint's 8328.

At chroma 3.8 the yellow-green cast shows up against a neutral background and disappears against anything with stronger colour. 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.

25.0 on the light-reflectance scale puts it in the middle third, which is the part of the scale with the fewest surprises. Works as a backdrop for artwork, furniture, or anything else in the room that is meant to stand out more than the walls do.

For a secondary wall, Vista Paint Desired Dawn gives a natural step up in brightness without feeling like a mismatch (roughly 45 LRV points apart).

By the numbers, Kilz Lincoln Green (TB-68) and this color are indistinguishable - delta-E 0.97, well under what the eye can separate. 4 other-brand colors land within delta-E 2 of this one - a well-populated part of the spectrum with several near-equivalents to choose from. This color reads consistently across most finishes, so the choice can come down to durability needs rather than how it changes the color.

It is lighter than 24 percent of the Vista Paint range. Vista Paint lists it in the K codes, alongside 1,318 other colors.
