Patches vs Cement grey
Where Patches belongs to PPG's range, Cement grey is a RAL Classic color. Hue-wise, Patches belongs to the greige-grey family and Cement grey to the grey family. Cement grey (LRV 24) reflects noticeably more light than Patches (LRV 21), a difference of 3 points that becomes especially apparent in rooms with limited natural light. The ΔE 7.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

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.
