Fun Yellow vs Optimistic Yellow

Both from Sherwin-Williams's palette. Both sit in the beige-yellow family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (78 vs 76), so they'll read as similarly Light in most lighting conditions. Both lean warm, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 10.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
