Outerspace

Pale enough to open a room, with a teal undertone strong enough to still read as a deliberate choice. Vista Paint catalogs it as Outerspace, 0686.

68.0 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 12.9 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 17 points apart in light reflectance).

Kilz Sailing Water (TB-53) runs close enough - delta-E 1.16 - that swapping brands should not change how the room looks. Matte or low-sheen suits it on walls; higher gloss will exaggerate the undertone.

It is lighter than 73 percent of the Vista Paint range. This is a crowded part of the scale - 406 colors measure within a point of 68.0 - so most brands will have something close. The name is not unique: Sherwin-Williams SW 6251 also sells a color called Outerspace, and it is not the same shade. Vista Paint lists it in the C codes, alongside 1,421 other colors.
