Visual kits for agents that need to design well
Pick what you're building, preview every kit on that surface, and hand your agent a complete visual system — fonts, colors, tokens, and component rules.

A resolutely flat two-color surface system. Vivid grass-green (#229f39) and deep cobalt-blue (#2b3386) are sovereign peers: either can fill an entire screen or section, with no neutral intermediary. All text is set in Space Mono at every scale from hero display down to captions, making the monospace grid the primary typographic voice rather than a code aesthetic. All shapes are sharp 90-degree rectangles, and section breaks use stacked parallel horizontal lines as a graphic band.

Each use below is named in the kit's brief and clears the checks for contrast, typography, and information density.
The same kit, applied to real screens. Nothing here is a mockup of a template — every surface is drawn from this kit's own tokens, type and treatments.
The same kit across 3 surfaces.
Generic output is a layout problem before it is a color problem. These rules ship inside the kit, so the agent building your project reads them too.

Typography is what language looks like. The right typeface sets the tone before a single word is read. Its rhythm, weight, and shape carry the brand.

## Overview A resolutely flat two-color surface system. Vivid grass-green (#229f39) and deep cobalt-blue (#2b3386) are sovereign peers: either can fill an entire screen or section, with no neutral intermediary. All text is set in Space Mono at every scale from hero display down to captions, making the monospace grid the primary typographic voice rather than a code aesthetic. All shapes are sharp 90-degree rectangles, and section breaks use stacked parallel horizontal lines as a graphic band. ## Personality - **Feels like:** tectonic, laconic, militant, graphic, institutional. - **Not like:** consumer SaaS warmth: rounded corners, friendly gradients, pastel tints softening the two brand colors, glassmorphism: frosted panels, blur overlays, translucent card surfaces, Swiss white-space minimalism: color fill is the organizing principle here, not open emptiness, dark-mode tech aesthetic: deep grey backgrounds, purple-blue gradients, neon accent strokes, lifestyle or stock photography. The visual language is dot-matrix halftone and vertical-stripe geometry only. ## Colors Every color captured from the source. Store all of them; a given screen renders only the subset it needs (a chart may use every data-viz color while a hero uses two). **Surfaces** - `#229f39`: background-primary 1 - `#2b3386`: background-secondary 2 - `#d3e2f2`: surface-light 9 - `#acb4cc`: surface-muted 10 - `#17882a`: surface-muted 16 - `#1e2776`: surface-dark-card 17 - `#1e2464`: surface-dark-muted 18 - `#3c4499`: surface-dark-secondary 19 **Ink / text** - `#ffffff`: ink-on-blue 13 - `#001500`: ink-on-green 14 - `#8890c4`: mutedForeground-dark 21 **Accents** - `#095dac`: accent 3 - `#22c847`: accent-light 15 **Data-viz series** - `#0c59a6`: data-viz 4 - `#0c549c`: data-viz 5 - `#1d4394`: data-viz 6 - `#1b7c65`: data-viz 11 - `#26595b`: data-viz 12 **Borders** - `#3d4599`: border-dark 20 **Other**
