Umbra grey vs Tranquil Dawn Color Comparison
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.

Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Tranquil Dawn returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Tranquil Dawn returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
