Firefly vs Dayroom Yellow
Firefly (Behr) and Dayroom Yellow (Farrow & Ball) come from different manufacturers. These are both beige-yellows, so the question isn't which hue to choose — it's where within beige-yellow to land. The 11-point LRV gap — 86 for Firefly vs 75 for Dayroom Yellow — means Firefly will open up a space more effectively. Where Firefly leans yellow, Dayroom Yellow reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 7.3 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Firefly vs Dayroom Yellow in Real Spaces
1 real room side by side. Firefly and Dayroom Yellow are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Firefly returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Firefly vs Dayroom Yellow Simulated Comparison
5 simulated room previews — drag the slider on each to see Firefly on one side and Dayroom Yellow on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
