Ada. A quiet off-white room where four jewel-tone colors are allowed to speak, and everything else stays in charcoal.

Ada operates as a daylight gallery: an off-white canvas with generous breathing room, a single humanist sans-serif doing all the voice work, and jewel-toned accent colors that appear only as deliberate punctuation marks. The visual system resists decoration — no gradients on buttons, no drop shadows on cards, no chrome competing with content. Instead, identity comes from a small, disciplined palette (forest green, periwinkle blue, candy pink, butter yellow) used as left-edge accent bars on stat cards and as filled pill buttons. Hierarchy is built through size contrast and whitespace, not color volume. Surfaces sit on a warm #f9f9f9 ground with #ffffff cards floating above. The hero's defining move is a heavily blurred photographic background that feels like looking through frosted glass — it adds warmth and depth without competing with the white headline that reads like editorial typography.

Ada

Brand2

  • Primary brand identity, filled dark buttons, dark accent bar on stat cards, announcement bar background — deep green that signals authority and trust without corporate blandness

  • Blue action color for filled buttons, selected navigation states, and focused conversion moments.

Accent2

  • Accent bar on stat cards, decorative soft surface washes — the most playful of the four accents, used sparingly to add warmth

  • Accent bar on stat cards, warmth punctuation — the warmest accent, appearing only on the 4th stat card as a visual rhythm closer

Neutrals5

  • Primary text, body copy, headings, hairline borders, dark UI surfaces — the near-black backbone of the entire interface, used at massive scale for borders and typography

  • Muted card borders and dark surface tints — a desaturated plum that appears on secondary containers

  • Decorative SVG fills, disabled input borders, neutral dividers

  • Page canvas, section backgrounds, subtle surface tier beneath cards — a warm off-white that softens the contrast of the interface

  • Card surfaces, elevated panels, chat widget container, inputs — the brightest tier of the surface stack
