Using this palette

Every tone here is desaturated except #B5651D, which stands in for oxidized metal or exposed brick and is deliberately the only note of real warmth in the set — real industrial interiors are almost entirely gray and brown with rust as the sole accent color, and this palette copies that ratio rather than inventing a more colorful version. #A9A9A9 is the lightest swatch and still reads as fairly heavy, so pair it with genuine white or cream if the layout needs real breathing room. Fits loft/coworking branding, craft/maker-space sites, or dark-mode developer tools; too heavy for anything meant to feel light or approachable.
