A focused workspace for serious UI theme work.

Free web palette tools stop at copy and paste. INS Theme Studio continues into semantic tokens, accessibility checks, imports, exports, and local project updates.

Color Engine

OKLCH scales that feel even

Generate perceptual 50-950 color scales with lightness interpolation and chroma tapering for usable extremes.

Harmony

Algorithmic combinations

Explore complementary, split, triadic, tetradic, analogous, monochromatic, square, and compound harmony logic.

Tokens

Editable semantic system

Customize primary, harmony, info, success, warning, danger, foreground, background, muted, accent, ring, and border tokens.

Import

Bring existing themes in

Import shadcn CSS variables, Tailwind v3/v4 theme output, and token JSON to continue work instead of starting over.

Export

Ship the format you need

Copy Tailwind v3 objects, Tailwind v4 @theme blocks, shadcn/ui CSS variables, and W3C-style token JSON.

Apply

Update local projects safely

Choose a local project, preview changed files, create backups, and update marked theme blocks without cloud access.

Designed for the moment after the palette looks good.

The hard part is not finding a nice blue. It is turning that color into a maintainable UI system that survives real components, dark mode, validation, export, import, and local project updates.

Project-safe apply.: Preview changes, create backups, and update marked theme blocks before touching production files.
Token-aware exports.: Use your own token names while keeping shadcn/ui aliases stable for real component libraries.
Offline client work.: Brand colors, screenshots, logos, and source files stay on the designer or developer's Mac.

INS Theme Studio workspace preview with dashboard components

Product screens built around real decisions.

Every screen is designed to answer a practical question: does this color system work, can I export it, and can I apply it safely?

Colors and token editor

Manual HEX, RGB, HSL, and OKLCH entry with semantic scales, surface tokens, and contrast validation.

Workspace preview

Preview generated tokens on realistic admin cards, charts, semantic buttons, alerts, and apply states.

Production exports

Copy Tailwind v3, Tailwind v4, shadcn/ui CSS variables, and token JSON with custom token names.

Safe local apply

Select a local project, preview changed files, create backups, and apply marked theme blocks safely.

From brand color to local project in four steps.

The workflow is intentionally local and reviewable, so the app feels like a professional tool instead of a disposable generator.

Choose or import

Pick a primary color, sample from a logo, or import an existing theme file.

Tune tokens

Adjust semantic colors, surface tokens, foreground roles, and harmony relationships.

Validate preview

Inspect realistic dashboard components, contrast results, and simulation views.

Export or apply

Copy production-ready theme output or safely update a selected local project.
