Design systems made simple
Desisy keeps tokens, components, and guidelines in sync - powered by Tailsys, the MCBILE Color System built on Tailwind v4. 37 color families in RGB, HEX, and OKLCH, extended with MCBILE brand ramps, MIX tokens, and Carbon, Race, and Chrome composite surfaces - one canon shared across every product, so design and code never drift apart.
Single source of tokens
Colors, type, and spacing defined once in Tailsys and used everywhere - solid tokens plus MIX tokens exposed as var(--color-*) across the whole stack.
Tailwind v4 plus brand families
Every Tailwind v4 hue in RGB, HEX, and OKLCH, extended with MCBILE brand ramps and special composite surfaces - Carbon, Race, and Chrome.
Drift detection
Catch hardcoded hex and OKLCH values before they reach production - components look up the canon instead of inventing color.
How it works
Define
Author the palette in the Tailsys specimen - mono colors, MIX tokens, and Carbon presets.
Generate
One command builds the dist CSS bundle and full spec from a single source of truth.
Stay in sync
Every product imports the same tokens; drift gets flagged before merge.
