Greenblack vs Mountain Pass
Both are Sherwin-Williams colors. Greenblack reads as green-grey, while Mountain Pass reads as blue-grey — two distinct hue families, not close cousins. At LRV 14 vs 4, Mountain Pass will read as the brighter of the two — a 9-point gap that matters most in north-facing or low-light rooms. They share a neutral quality — useful to know if you're layering them in the same space. At ΔE 20.0, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Greenblack vs Mountain Pass in Real Spaces
2 real rooms side by side. Seeing Greenblack and Mountain Pass 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. Mountain Pass returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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 Mountain Pass will make the room feel meaningfully brighter than Greenblack would.

5 simulated room previews — drag the slider on each to see Greenblack on one side and Mountain Pass 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.
