Forget-Me-Not vs Green Onyx
Both from Sherwin-Williams's palette. Hue-wise, Forget-Me-Not belongs to the blue-purple family and Green Onyx to the green-greige family. Green Onyx (LRV 31) reflects noticeably more light than Forget-Me-Not (LRV 16), a difference of 16 points that becomes especially apparent in rooms with limited natural light. Forget-Me-Not runs cool while Green Onyx is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 44.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Green Onyx will make the room feel meaningfully brighter than Forget-Me-Not would.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Green Onyx reflects noticeably more light off the walls, making the space read more open than Forget-Me-Not.
