Colonnade Gray vs Special Gray

Colonnade Gray runs warm while Special Gray is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 28.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

Digital color is approximate.
