Airbnb

Reference it for

• Restrained accent strategy: keep #ff385c (Rausch Coral) for the logo and one or two brand moments only, render every CTA in carbon-black (#222222) so the colour reads as signature not system
• Centred hero formula: tight black geometric-sans headline at ~64px with negative letter-spacing over a muted grey (#6a6a6a) two-to-three-line sub, then one solid black pill button
• Paper-on-paper depth: #f7f7f7 page canvas with #ffffff card surfaces, almost no visible elevation, photography supplies the contrast
• Airbnb Cereal VF style display: a humanist geometric sans run heavy (700) for headlines, 400 for body, on a compact scale (11/14/20/22/28px)
• 20px rounded corners as the one generous radius: bleed images edge-to-edge inside a 20px frame while everything else stays compact (4/8px)
• Hairline header on white: thin #ebebeb bottom border, left wordmark, right-aligned text nav plus one filled dark CTA
• Soft layered popover shadow recipe: rgba(0,0,0,0.02) 0 0 0 1px, rgba(0,0,0,0.04) 0 2px 6px, rgba(0,0,0,0.1) 0 4px 8px for search bars and floating panels
• Muted-grey supporting copy (#6a6a6a) against carbon headlines for a quiet two-tone text hierarchy

Do not copy

• The Rausch Coral #ff385c itself and the Rausch Deep #e00b41 gradient pair, both are unmistakably Airbnb
• The airbnb.org / airbnb wordmark and the Belo loop logomark
• Airbnb Cereal VF, a proprietary licensed typeface, substitute a comparable geometric humanist sans
• The exact search-bar pill module (segmented where/when/who control) which is an Airbnb signature
• The literal emergency-housing nonprofit framing and donation flow specific to airbnb.org
