Brilliant Blue vs RAL 640-5
Brilliant Blue is a Benjamin Moore color while RAL 640-5 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 9.4, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.
