Atmosphere vs French Gray
Where Atmosphere belongs to Dulux's range, French Gray is a Farrow & Ball color. Atmosphere reads as blue, while French Gray reads as beige-greige — two distinct hue families, not close cousins.

Atmosphere runs cool while French Gray is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 21.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
