Teton Blue vs RAL 820-2 in Real Spaces
3 real rooms side by side. Teton Blue and RAL 820-2 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.
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. RAL 820-2 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. RAL 820-2 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. RAL 820-2 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Teton Blue vs RAL 820-2 Simulated Comparison
5 simulated room previews — drag the slider on each to see Teton Blue on one side and RAL 820-2 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.
