Blue Spruce vs Onyx in Real Spaces
2 real rooms side by side. Seeing Blue Spruce and Onyx in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Blue Spruce 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. Blue Spruce returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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