Hemlock vs Cathedral Glass
Hemlock (Benjamin Moore) and Cathedral Glass (PPG) come from different manufacturers. Hemlock reads as blue, while Cathedral Glass reads as blue-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 29 vs 29 — so neither will read significantly brighter or darker than the other. A ΔE of 1.9 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Hemlock vs Cathedral Glass Simulated Comparison
5 simulated room previews — drag the slider on each to see Hemlock on one side and Cathedral Glass 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.
