Cement grey vs Ruby Violet
Cement grey (RAL Classic) and Ruby Violet (Sherwin-Williams) come from different manufacturers. Cement grey reads as grey, while Ruby Violet reads as grey-purple — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 24 vs 24 — so neither will read significantly brighter or darker than the other. A ΔE of 20.0 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Cement grey vs Ruby Violet Simulated Comparison
5 simulated room previews — drag the slider on each to see Cement grey on one side and Ruby Violet 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.
