Cosmic Blue vs Sky Blue
Cosmic Blue (Behr) and Sky Blue (Little Greene) come from different manufacturers. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 15-point LRV gap — 61 for Sky Blue vs 47 for Cosmic Blue — means Sky 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 7.5 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 Sky Blue in Real Spaces
1 real room side by side. Cosmic Blue and Sky 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.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Sky Blue reflects noticeably more light off the walls, making the space read more open than Cosmic Blue.

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