Black green reads as blue-green, while Still Water reads as blue-grey — two distinct hue families, not close cousins. The 3-point LRV gap — 10 for Still Water vs 7 for Black green — means Still Water will open up a space more effectively. A ΔE of 14.0 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Black green vs Still Water in Real Spaces
3 real rooms side by side. Seeing Black green and Still Water in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Still Water has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Still Water has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Still Water has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Black green vs Still Water Simulated Comparison
5 simulated room previews — drag the slider on each to see Black green on one side and Still Water 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.
