Blue lilac vs Concrete grey
Both from RAL Classic's palette. Blue lilac reads as blue-purple, while Concrete grey reads as grey — two distinct hue families, not close cousins.

With a ΔE of 36.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
