Mellow Yellow vs Dayroom Yellow
Where Mellow Yellow belongs to Benjamin Moore's range, Dayroom Yellow is a Farrow & Ball color. Both sit in the beige-yellow family, which is useful context if you're narrowing within a single hue direction. Mellow Yellow (LRV 78) reflects noticeably more light than Dayroom Yellow (LRV 75), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Mellow Yellow runs yellow while Dayroom Yellow is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 3.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
