# OpenSea — Style Reference
> Black trading terminal with frosted blue wireframes.
**Theme:** dark
Source measurements are normalized; roles and recommendations are interpreted. Font summary lists are independent, not paired by position. HTML examples are reconstructions, not source components.
OpenSea runs on a near-black canvas with paper-white text and a single cool blue accent (#83c3ff) that signals links, verified badges, and outlined interactive elements. Surfaces are stratified in tiny tonal steps (#080809 → #141415 → #1b1d1f → #26272d) so cards appear to float on the page through hairline inset white-alpha rings (rgba(255,255,255,0.08)) rather than drop shadows. Typography is restrained: gtAmerica at 12–16px for almost everything, with 20–32px reserved for section headers, and gtAmericaMono stepping in for prices, addresses, and numeric data. The layout is a three-pane shell — slim left icon rail, fluid center content, fixed right sidebar — and the rhythm stays dense, with 8–12px gutters and 4px/8px corner radii throughout.
