Stained Glass vs RAL 620-4
Stained Glass is a Benjamin Moore color while RAL 620-4 comes from RAL Effect. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. At LRV 13 vs 9, Stained Glass will read as the brighter of the two — a 4-point gap that matters most in north-facing or low-light rooms. At ΔE 6.0, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.
