Blue Spa vs RAL 720-M
Blue Spa is a Benjamin Moore color while RAL 720-M comes from RAL Effect. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction.

At ΔE 6.7, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.
