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.
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 high-energy kit operating on exactly two surfaces, near-black (#1a1a1a) and acid-green (#1bff59), as the only valid backgrounds; no whites or neutrals anywhere. Barlow Condensed headings scale to poster dimensions, sometimes rotated 90° to fill the full container height. Space Mono is the universal face for body copy, labels, navigation, and metadata. Pill-shaped CTA buttons render in the inverse surface color, and a visible surface-toggle switches the entire UI between the two colors.

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 high-energy kit operating on exactly two surfaces, near-black (#1a1a1a) and acid-green (#1bff59), as the only valid backgrounds; no whites or neutrals anywhere. Barlow Condensed headings scale to poster dimensions, sometimes rotated 90° to fill the full container height. Space Mono is the universal face for body copy, labels, navigation, and metadata. Pill-shaped CTA buttons render in the inverse surface color, and a visible surface-toggle switches the entire UI between the two colors. ## Personality - **Feels like:** tectonic, phosphorescent, clandestine, surgical, monolithic. - **Not like:** bubbly consumer SaaS with pastel gradients and rounded cards, glassmorphism or frosted-panel overlays on any surface, dark-mode dashboard grayscale spectrum with sidebar navs and data widgets, crypto/Web3 maximalism with neon-on-dark token-price tickers, music streaming tile grids with square album art and play-count metadata. ## 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). **Brand** - `#1bff59`: brand-primary 1 **Surfaces** - `#1a1a1a`: dark-surface 2 - `#252525`: dark-surface-variant 3 **Ink / text** - `#e8e8e8`: ink-on-dark 4 - `#0d0d0d`: ink-on-green 5 - `#e4e4e4`: outer-context 6 - `#0a3318`: muted-ink-on-green 9 **Accents** - `#7cfc9c`: accent-tint 7 - `#1d8032`: accent-shade 8 **Data-viz series** - `#1bff59`: data-viz 17 - `#7cfc9c`: data-viz 18 - `#e8e8e8`: data-viz 19 - `#8f8f8f`: data-viz 20 - `#333333`: data-viz 21 **Borders** - `#333333`: border-dark 13 - `#0ec842`: border-light 14 **Other** - `#7c7b7c`: muted 10
