Colonial Yellow vs Summer Day
Both from Sherwin-Williams's palette. Colonial Yellow reads as beige-yellow, while Summer Day reads as beige — two distinct hue families, not close cousins. Colonial Yellow (LRV 60) reflects noticeably more light than Summer Day (LRV 47), a difference of 12 points that becomes especially apparent in rooms with limited natural light. Both lean warm, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 15.0, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
