Fortitude vs Rushing River
Both from Sherwin-Williams's palette. Fortitude reads as grey, while Rushing River reads as greige-grey — two distinct hue families, not close cousins. Fortitude (LRV 56) reflects noticeably more light than Rushing River (LRV 34), a difference of 22 points that becomes especially apparent in rooms with limited natural light. Fortitude runs neutral while Rushing River is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 16.0, the contrast is hard to miss.
