More about Passive
Passive is the cool counterpart to the warm greiges — a light, true gray at LRV 60 with a clean blue base and none of the beige that defines Agreeable or Repose. It's the pick for a crisp, modern, cool-gray room, especially where you want gray to read as gray rather than greige.
That cool base is the consideration: in north light it can lean slightly blue, so it's strongest with warm or ample light, or where you want that crisp quality on purpose. Behr Mexican Silver is a near-identical match, with Benjamin Moore Perspective very close.
