The decision for this particular color
First Star can be considered for bathroom if its color and depth suit the space; the first design question is an almost-white gray beside white trim. First Star is deep enough to be a gray-white rather than one of the highest-reflectance whites.
Why the white doors and silver-gray tile relationship matters
White doors offer a stable comparison for deciding whether the gentle gray boundary is visible enough from the entrance.
First Star has an LRV of 69; Sherwin-Williams Eider White SW-7014 is 73. The difference is 4 points, with Eider White returning more light under the reference measurement.
Let tile and porcelain set the limits
Put First Star against the basin, tile background and grout simultaneously. A close white palette can expose small differences at every joint. Inspect under the vanity light and in the mirror, where reflections bring additional surfaces into the view before deciding which white should lead.
Separate the palette from the moisture specification
View the wall and doors from the room entrance; keep First Star if the gentle separation is sufficient. The undertones and neighboring colors covers that related choice. The daylight and evening-light checks covers that related choice.
Choose a Sherwin-Williams coating appropriate to the bathroom surface and follow the manufacturer's preparation and application guidance. Color SW-7646 does not identify a moisture-control system. Ventilation, substrate condition and the intended finish are separate decisions; approve the color under the real vanity lighting before ordering the full paint quantity. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
