Teton Blue vs Vast Lake in Real Spaces
2 real rooms side by side. Teton Blue and Vast Lake 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. The distinction reads clearly at room scale, making the choice between them concrete.
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

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