Teton Blue vs RAL 150-M
Teton Blue (Behr) and RAL 150-M (RAL Effect) come from different manufacturers. Hue-wise, Teton Blue belongs to the blue-grey family and RAL 150-M to the beige-greige family. Their light reflectance values are nearly the same — 31 vs 33 — so neither will read significantly brighter or darker than the other. A ΔE of 17.2 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Teton Blue vs RAL 150-M in Real Spaces
3 real rooms side by side. Seeing Teton Blue and RAL 150-M 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
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. The distinction reads clearly at room scale, making the choice between them concrete.
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

Teton Blue vs RAL 150-M Simulated Comparison
5 simulated room previews — drag the slider on each to see Teton Blue on one side and RAL 150-M 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.
