Ghostty — design system & UI screens
Restrained dark landing centered on a single framed terminal window rendering ASCII art, with download and documentation CTAs and almost no chrome. GPU-accelerated, platform-native.
This is a static, crawlable rendering for search & AI engines. The interactive version — filters, live decode console, copy & export — is at https://mozaika.design/website/ghostty.
Decoded design system
Ghostty's decoded design system: background #0F0F11, text #F0F0F4, accent #3551F3, link #14242D, primary #70B8DB; type scale h1 16px / h2 16px / body 14px; 4px spacing base; 8px base radius. The single interactive/action color is #0F0F11 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Using these colors
- Action color
#0F0F11— the single interactive color; only on things you click or must notice, never large fills. - accent
#3551F3— accent for emphasis — keep it rare on the page. - primary
#70B8DB— a brand color — but the call-to-action uses #0F0F11, not this. - link
#14242D— fails contrast on the background (~1.2:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference). - secondary
#BF8CD9— optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
