Astronomical vs Teton Blue
Astronomical and Teton Blue come from the same Behr collection. Hue-wise, Astronomical belongs to the grey family and Teton Blue to the blue-grey family. The 24-point LRV gap — 31 for Teton Blue vs 7 for Astronomical — means Teton Blue will open up a space more effectively. Where Astronomical leans green, Teton Blue reads blue — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 31.5 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Astronomical vs Teton Blue in Real Spaces
1 real room side by side. Seeing Astronomical and Teton Blue in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Teton Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

5 simulated room previews — drag the slider on each to see Astronomical on one side and Teton 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.
