Cupola Yellow vs White Iris

Both from Sherwin-Williams's palette. Hue-wise, Cupola Yellow belongs to the beige-yellow family and White Iris to the blue-white family. White Iris (LRV 76) reflects noticeably more light than Cupola Yellow (LRV 53), a difference of 23 points that becomes especially apparent in rooms with limited natural light. Cupola Yellow runs warm while White Iris is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 32.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
