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.

Acid-lime (#f1ff2a) fills every screen and section as the pervasive surface; text and controls sit directly on it. Typography is condensed, oversized, and set entirely in uppercase, from display headings down to metadata, using Barlow Condensed at 900 weight. Space Mono carries all technical strings such as coordinate notation, dates, and timestamps. Imagery arrives as large rounded-corner die-cuts (1.5rem+ radius) dropped onto the lime field with no frame or shadow. The palette is radically reduced to lime, near-black (#0c0e00), and dark forest green (#2f3412 / #3f5b45), drawing drama from scale and contrast rather than color variety.

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.

## Overview Acid-lime (#f1ff2a) fills every screen and section as the pervasive surface; text and controls sit directly on it. Typography is condensed, oversized, and set entirely in uppercase, from display headings down to metadata, using Barlow Condensed at 900 weight. Space Mono carries all technical strings such as coordinate notation, dates, and timestamps. Imagery arrives as large rounded-corner die-cuts (1.5rem+ radius) dropped onto the lime field with no frame or shadow. The palette is radically reduced to lime, near-black (#0c0e00), and dark forest green (#2f3412 / #3f5b45), drawing drama from scale and contrast rather than color variety. ## Personality - **Feels like:** tectonic, uncompromising, poster-loud, kinetic, raw. - **Not like:** bubbly consumer SaaS with soft shadows, pastel accents, and rounded-corner illustration systems, dark-mode glassmorphism with frosted-panel overlays and neon gradient accents, outdoor-gear corporate polish using muted earth tones, clean light-weight sans, and full-bleed nature stock heroes, soft editorial readability in the vein of independent editorial publishing: centered body columns, light-gray section br, festival hype maximalism with competing neon colors, confetti textures, and layered badge clusters all fighting for the. ## 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** - `#f1ff2a`: brand-surface 1 - `#fdff2e`: brand-surface-alt 2 - `#e8f42f`: brand-surface-muted 3 - `#eefc2a`: brand-surface-variant 4 **Ink / text** - `#0c0e00`: ink 5 - `#010303`: ink-absolute 6 **Accents** - `#2f3412`: accent 7 - `#3f5b45`: accent-secondary 8 - `#a4ac74`: muted-accent 11 **Data-viz series** - `#ce9420`: data-viz 9 - `#7ab648`: data-viz 10 - `#f1ff2a`: data-viz 14 - `#2f3412`: data-viz 15 - `#0c0e00`: data-viz 16 - `#7ab648`: data-viz 17 - `#ce9420`: data-viz 18 - `#6dbf8d`: data-viz 19 **Other** - `#999758`: muted 12 - `#314a54`: muted-dark 13 **Semantic roles, light**
