Light grey vs Windy Blue in Real Spaces
2 real rooms side by side. Seeing Light grey and Windy Blue 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. Light grey reflects noticeably more light off the walls, making the space read more open than Windy Blue.
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. Light grey returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Light grey vs Windy Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Light grey on one side and Windy 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.
