Festoon Aqua vs Spearmint

Both from Sherwin-Williams's palette. Festoon Aqua reads as blue, while Spearmint reads as green — two distinct hue families, not close cousins. Festoon Aqua (LRV 46) reflects noticeably more light than Spearmint (LRV 42), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 7.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
