Description
I worked on many apps where each customer needs their own branded theme.The problem is that you can't just shift hue and call it a day. Yellow at 50% lightness looks completely different from blue at 50%.That's why I built this library to generate perceptually uniform themes. Zero dependencies, runs at runtime, outputs CSS vars, Tailwind tokens, SCSS, or JSON. Ships with presets for shadcn/ui and MUI.try it out quickly: npx hextimate "#006677"

Could you build this?
Yes It is a client-side color science utility library implementing well-documented OKLCH mathematical conversion formulas and contrast algorithms to produce CSS palette variables.
