Hue-Locked Color Palette Generator

Used by developers, writers, and creators worldwide.

A hue-locked color palette generator solves a common design problem: picking multiple colors that feel intentional together without hiring a brand consultant. It constrains every generated swatch to one hue family — blue, green, red, and six others — while varying saturation and lightness across the set. The result is a palette that reads as unified but gives you real tonal range to work with. Designers use this for UI component libraries, data dashboards, and brand systems where visual cohesion matters. Choose your hue, set between 2 and 10 colors, and regenerate as many times as you need. Each run produces a fresh variation within the same color family.

How to use

  1. Choose your options above
  2. Click Generate
  3. Copy your result

Detailed instructions

  1. Select your desired hue family from the dropdown — options include blue, green, red, purple, and others.
  2. Set the Colors count to match how many distinct swatches your project needs, between 2 and 10.
  3. Click Generate to produce a fresh palette locked to your chosen hue family.
  4. Regenerate as many times as needed until the tonal spread and saturation feel right for your use case.
  5. Copy individual hex codes from the grid and paste them into your design tool, stylesheet, or color token file.

Use Cases

  • Generating 5 blue token stops — from background tint to active state — for a Figma component library
  • Coloring 7 data series in a Recharts or D3 line chart without clashing hues
  • Building hover, focus, and disabled button states that stay within a brand's green family
  • Creating gradient stops for a single-hue hero section in a Webflow or Framer landing page
  • Mapping category swatches in a Notion or Airtable dashboard that prints cleanly in grayscale

Tips

  • Generate at count 7 first, then remove the swatches that feel redundant — easier than adding more later.
  • For dark-mode UI, regenerate until your darkest swatch is deep enough to use as a background at WCAG AA.
  • Warm hues like red and orange produce palettes that look noticeably different each run — regenerate more freely with those.
  • Pair a hue-locked palette with one neutral gray set to ground the design without introducing competing hues.
  • For data charts, avoid counts above 7 within one hue family — beyond that, adjacent colors become too similar to distinguish reliably.
  • Copy your favorite run's hex values immediately — there's no history, and a good set is easy to lose.

FAQ

how is hue-locked different from a monochromatic palette

A monochromatic palette uses a single fixed hue angle — every color is literally the same hue, just lighter or darker. Hue-locked palettes allow slight variation around the chosen family, so the results feel more natural and easier to distinguish side by side in a real layout. The difference is subtle but noticeable once colors are placed next to each other at small UI sizes.

how many colors should I generate for a design token system

Most systems use 5 to 9 stops per hue — enough to cover background tints, borders, text, and interactive states. Start with 5 and check whether adjacent swatches have enough lightness contrast for WCAG compliance. If two stops look too similar at small sizes, bump the count to 7 for a wider tonal spread.

how do I use the generated palette in Figma or CSS

Copy each hex code and paste it as a color style in Figma or as a CSS custom property in your stylesheet. Name them systematically — for example, --color-blue-100 through --color-blue-900 — so they slot into a token structure. This makes theming or swapping the palette straightforward without hunting down individual values later.
