Believable Buff vs Sea Mariner
Believable Buff and Sea Mariner come from the same Sherwin-Williams collection. Believable Buff reads as beige, while Sea Mariner reads as blue-grey — two distinct hue families, not close cousins. The 52-point LRV gap — 59 for Believable Buff vs 7 for Sea Mariner — means Believable Buff will open up a space more effectively. Where Believable Buff leans warm, Sea Mariner reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes.
