Cosmic Blue vs Dix Blue
Where Cosmic Blue belongs to Behr's range, Dix Blue is a Farrow & Ball color. Cosmic Blue reads as blue, while Dix Blue reads as blue-grey — two distinct hue families, not close cousins. Cosmic Blue (LRV 47) reflects noticeably more light than Dix Blue (LRV 41), a difference of 6 points that becomes especially apparent in rooms with limited natural light. Cosmic Blue runs blue while Dix Blue is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 11.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cosmic Blue vs Dix Blue in Real Spaces
5 real rooms side by side. Seeing Cosmic Blue and Dix Blue in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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 — Cosmic Blue gives the walls a little more lift.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Cosmic Blue reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Cosmic Blue reads slightly lighter here — a subtle but real difference in how open the space feels.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. Cosmic Blue reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Cosmic Blue reads slightly lighter here — a subtle but real difference in how open the space feels.

Cosmic Blue vs Dix Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Cosmic Blue on one side and Dix Blue 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.
