Airbnb uses a coral red as its brand color, featured in its logo, the “Bélo.” The classic shade is called “Rausch”; the current website and app use a slightly pinker coral. The rest of the interface relies on whites and grays. The HEX codes are commonly used values, not published as an official specification.
These are commonly used reference values; they can vary by source, material or screen. Brand names and colors belong to their owners; this page only lists color codes for information.
