Inferno vs Primary Red

Inferno (LRV 20) reflects noticeably more light than Primary Red (LRV 9), a difference of 11 points that becomes especially apparent in rooms with limited natural light. Inferno runs red while Primary Red is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 21.7, the contrast is hard to miss.
