Color Psychology

Bright · Optimistic

Brilliant Impression brings light into spaces that lack it — kitchens, breakfast nooks, kids' rooms wake up under it. The trick with yellow is restraint: lean toward the muted/buttery end if you want it on walls; reserve high-chroma versions for accents and trim.
