At ΔE 38.8, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Half Dome vs Still Water in Real Spaces
6 real rooms side by side. Seeing Half Dome 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.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Half Dome returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that Half Dome will make the room feel meaningfully brighter than Still Water would.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Half Dome will make the room feel meaningfully brighter than Still Water would.
Home Office
In a home office, wall color sits in your peripheral vision for hours at a time, so temperature and undertone matter more than you might expect. The LRV gap is large enough that Half Dome will make the room feel meaningfully brighter than Still Water would.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The LRV gap is large enough that Half Dome will make the room feel meaningfully brighter than Still Water would.
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. Half Dome returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Half Dome vs Still Water Simulated Comparison
5 simulated room previews — drag the slider on each to see Half Dome 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.
