Window grey vs V438
Where Window grey belongs to RAL Classic's range, V438 is a Tikkurila color. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. They have nearly identical light reflectance values (36 vs 37), so they'll read as similarly Medium in most lighting conditions. The ΔE 4.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
