Mouse grey vs Grapy
Where Mouse grey belongs to RAL Classic's range, Grapy is a Sherwin-Williams color. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (18 vs 16), so they'll read as similarly Dark in most lighting conditions. The ΔE 6.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
