Cook's Blue vs Evergreen Fog in Real Spaces
7 real rooms side by side. Seeing Cook's Blue and Evergreen Fog in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Evergreen Fog has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The brightness difference is modest but present — Evergreen Fog gives the walls a little more lift.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The brightness difference is modest but present — Evergreen Fog gives the walls a little more lift.
Home Office
In a home office, wall color sits in your peripheral vision for hours at a time, so temperature and undertone matter more than you might expect. The brightness difference is modest but present — Evergreen Fog gives the walls a little more lift.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The brightness difference is modest but present — Evergreen Fog gives the walls a little more lift.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Evergreen Fog has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. The brightness difference is modest but present — Evergreen Fog gives the walls a little more lift.
