A ΔE of 19.5 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Teton Blue vs Blue grey in Real Spaces
4 real rooms side by side. Seeing Teton Blue and Blue grey 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. Teton Blue reflects noticeably more light off the walls, making the space read more open than Blue grey.
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.
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. Teton Blue 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. Teton Blue 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 Blue grey Simulated Comparison
5 simulated room previews — drag the slider on each to see Teton Blue on one side and Blue grey 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.
