Cosmic Blue vs Spectra Blue
Cosmic Blue (Behr) and Spectra Blue (Benjamin Moore) come from different manufacturers. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. The 9-point LRV gap — 56 for Spectra Blue vs 47 for Cosmic Blue — means Spectra Blue will open up a space more effectively. Both share a blue character, which means they'll respond to light and surrounding materials in similar ways. ΔE 5.2 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.
Cosmic Blue vs Spectra Blue in Real Spaces
1 real room side by side. Cosmic Blue and Spectra Blue 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.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Spectra Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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