June Day vs Regale Blue

Both from Sherwin-Williams's palette. June Day reads as beige, while Regale Blue reads as blue — two distinct hue families, not close cousins. June Day (LRV 63) reflects noticeably more light than Regale Blue (LRV 42), a difference of 21 points that becomes especially apparent in rooms with limited natural light. June Day runs warm while Regale Blue is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 72.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
