Caffeine vs Mouse's Back
Where Caffeine belongs to Behr's range, Mouse's Back is a Farrow & Ball color. Caffeine reads as greige-grey, while Mouse's Back reads as beige-greige — two distinct hue families, not close cousins. Mouse's Back (LRV 26) reflects noticeably more light than Caffeine (LRV 20), a difference of 6 points that becomes especially apparent in rooms with limited natural light. Caffeine runs red while Mouse's Back is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 6.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

Caffeine vs Mouse's Back in Real Spaces
2 real rooms side by side. Caffeine and Mouse's Back 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.
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 brightness difference is modest but present — Mouse's Back gives the walls a little more lift.
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. Mouse's Back reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
