Antique Slate vs Grey Blue
Antique Slate (PPG) and Grey Blue (RAL Classic) come from different manufacturers. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 9 vs 7 — so neither will read significantly brighter or darker than the other. A ΔE of 12.0 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Digital color is approximate.
