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.

Front Door

Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Slate grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
