Prairie Day

This sits close to white on the light meter but keeps its blue undertone clearly enough to be picked out of a lineup of whites. Vista Paint lists it as Prairie Day (7331).

Light reflectance measures 72.0, which is enough to keep a room bright without bouncing light around. At chroma 10.9 the blue undertone is clear in daylight and softer under lamps.

A warm bulb is the easiest fix if this reads colder than expected once it is on the wall. A good fit for bedrooms and nurseries, where softness matters more than intensity. If a second wall color is wanted in the same room, Dunn-Edwards Angel Feather keeps the jump obvious rather than muddy (roughly 15.1 LRV points from this one).

Behr Sapphireberry (550C-2) runs close enough - delta-E 1.05 - that swapping brands should not change how the room looks. 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 77 percent of the Vista Paint range. Vista Paint lists it in the K codes, alongside 1,318 other colors.
