Grey white vs Mushroom
Where Grey white belongs to RAL Classic's range, Mushroom is a Sherwin-Williams color. Grey white reads as greige-grey, while Mushroom reads as beige-greige — two distinct hue families, not close cousins. Grey white (LRV 67) reflects noticeably more light than Mushroom (LRV 57), a difference of 10 points that becomes especially apparent in rooms with limited natural light. The ΔE 6.4 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. Before committing to either color, test physical samples in your own space under the light you actually live with.
