Palette Generator for OKLCH color scales, schemes, and CSS variables

• Primary color scale generation

  Generate a full 50, 100, 200 through 950 color scale from one base color for Tailwind-style themes, CSS variables, and design tokens.

• Color scheme generation

  Create monochrome, analogous, complementary, and triadic schemes for primary, secondary, accent, and contrast roles.

• OKLCH lightness control

  Use OKLCH to produce smoother lightness and chroma transitions, reducing the uneven jumps common in HSL-based scales.

• Neutral scale output

  Generate neutral colors for surfaces, borders, muted text, cards, and background layers.

• Recommended text color

  Each swatch recommends black or white text and shows the contrast ratio for quick readability checks.

• Interface preview

  Preview buttons, links, badges, and cards to see how the palette behaves in a realistic UI composition.

• CSS and JSON export

  Export CSS variables and structured JSON for frontend projects, component libraries, and design token workflows.

• Base color

  The main color that anchors the palette, often used for primary buttons, links, selected states, and key brand moments.

• Color scale

  A sequence of related colors across lightness levels. Frontend systems often use 50 to 950 to move from light tints to deep shades.

• Monochrome palette

  A palette built around one hue by adjusting lightness and chroma. It works well for restrained tools and operational interfaces.

• Analogous palette

  A palette using neighboring hues on the color wheel. It creates natural transitions for brand surfaces and supporting UI colors.

• Complementary palette

  A palette using opposing hues for stronger contrast, useful for emphasis, alerts, and marketing surfaces when used carefully.

• Triadic palette

  A palette using hues spaced around the color wheel. It can create rich visual systems but needs controlled saturation and clear roles.

• OKLCH

  A perceptual color space that makes lightness changes more predictable, especially for color scales and dark mode palettes.

• Design token

  A named value that stores color decisions so design tools, CSS, component libraries, and multi-theme systems can share the same source.

1. 1

   Enter a base color in Hex, RGB, HSL, or OKLCH format.

2. 2

   Choose a mode: monochrome for stable interfaces, analogous for natural harmony, complementary for emphasis, or triadic for richer systems.

3. 3

   Choose a style: soft, balanced, vivid, or dark to control overall chroma and lightness direction.

4. 4

   Review the primary scale, scheme colors, and interface preview to confirm hierarchy across buttons, links, badges, and cards.

5. 5

   Click any swatch to copy a single value, or copy CSS variables / JSON for your project.

• Primary scale names follow the 50 to 950 convention used by Tailwind-style themes and many design systems.
• CSS output includes primary, scheme, and neutral variables that can be moved into global.css, theme.css, or component library configuration.
• JSON output keeps primary, scheme, and neutral groups separate for config files, documentation sites, and token pipelines.
• Every swatch is copyable, which helps during browser debugging, design review, and quick theme experiments.
• Recommended text color and contrast ratios help decide whether a color is better suited for background, surface, or text usage.
• Random base color is useful for exploring visual direction, while presets help start from common brand-friendly palettes.
• The interface preview shows how primary buttons, secondary buttons, badges, links, and cards work together.

If the base color comes from a design file, screenshot, or older CSS, confirm its exact value in Color Converter before generating the scale. Once the palette is ready, test important text and action pairs with Contrast Checker ; when those colors become hero backgrounds, soft accents, or campaign visuals, shape the transition in Gradient Generator instead of creating a separate visual language.

• Website theme design

  Expand one brand color into a usable set for buttons, links, backgrounds, borders, and emphasis.

• Component library color rules

  Create consistent color scales and state colors for Button, Badge, Alert, Tabs, Input, and similar components.

• Dark mode preparation

  Generate darker palette variants and neutral scales for background layers, borders, and readable interface states.

• Design token organization

  Export CSS variables and JSON for frontend themes, documentation, token files, and design system automation.

• Brand color expansion

  Turn a single brand color into light backgrounds, standard actions, deep accents, and readable text combinations.

• Data visualization support colors

  Use analogous, complementary, or triadic colors as starting points for charts, then validate contrast separately.

• Landing page and campaign design

  Generate coordinated colors for hero sections, CTA buttons, badges, and marketing cards.

• Admin dashboard theming

  Build a stable color baseline for sidebars, table states, filters, dashboard cards, and system feedback.

• Decide what the base color is for before generating the palette: brand identity, action color, link color, data color, or status color.
• Avoid using the 500 step everywhere. Backgrounds, borders, hover states, and deep emphasis should use different scale positions.
• Do not judge body text readability by appearance alone; confirm foreground/background pairs with a contrast checker.
• Do not simply invert a light palette for dark mode. Review surfaces, borders, text, and accents as a separate theme.
• Store final colors as tokens instead of scattering near-duplicate hex values across pages.
• If a brand color is too bright or too dark, adjust lightness and chroma first before changing hue.
• Keep chart colors and UI action colors separate when possible, so visual semantics do not become overloaded.
• Before release, test buttons, links, form states, alerts, disabled states, and focus states in the real interface.

• Color scales are algorithmic. Final brand fit still requires human review.
• Recommended black or white text is based on the current swatch. Complex backgrounds, images, and gradients need separate testing.
• OKLCH is increasingly common in modern design systems, but older toolchains may still need Hex or RGB output.
• Triadic and complementary schemes can become visually loud. Use them with controlled area, saturation, and role assignment.
• This tool generates palette data and variables; it does not rewrite your Tailwind config, CSS files, or design source files automatically.
• For accessibility-sensitive work, validate final foreground/background pairs in the contrast checker.
