Outdoor Cloud

#b1a4a3
Notes

Outdoor Cloud (#B1A4A3) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (4°, 8%, 67%) places it in the muted band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Outdoor
adjective

English compound out + door — sharing root with German außerhalb. As a color modifier, outdoor implies a neutral-and-natural-and-weather-exposed quality, the neutral color of L-L-Bean-and-Patagonia outdoor-clothing weather-exposed-and-utilitarian outdoor-and-camping textile-finish surface. Sits at the neutral-and-traditional end of the grid, parallel to natural and weathered in usage.

Cloud
noun

Suspended water droplets or ice crystals in the atmosphere — cumulus, stratus, cirrus, the entire taxonomy of cloud forms classified by Luke Howard in 1803. The color refers to the average reflectance of a fair-weather cumulus seen from below: a soft, very pale neutral gray with the optical brightness of small water droplets scattering all wavelengths nearly equally. Lighter than mist, warmer than ice.
