Large heading sample
This is how normal body text looks in your combination. Check the badges above: AA is the everyday standard (4.5:1 for normal text), AAA is the enhanced level (7:1), and UI elements need at least 3:1.

Design that feels alive
This mockup wears your exact palette — navbar, hero, buttons, cards, text, background and footer all update the moment your colors change.
Ship designs in hours, not weeks.
Accessible colors out of the box.
Share palettes with one link.
Colors are mapped by role: the most vibrant color becomes the primary, the lightest swatch the background and the darkest the text — so any palette reads like a real website.

CSS export produces :root variables (--color-1 … --color-5); JSON includes HEX, RGB and HSL for every swatch; PNG/SVG render a shareable palette board.
Design tokens
| Token | Value |

Primary, secondary and accent come from your palette; background, surface, text, muted and border are derived automatically; success, warning and error use accessible defaults (#16A34A, #D97706, #DC2626).

How to use this AI color palette generator
- Describe your idea. Type the mood you want — “calm ocean blue”, “luxury gold”, “cozy autumn” — or leave it empty for a random palette. The interpretation happens on your device, instantly.
- Choose a harmony. Keep Random for exploration, or pick Monochromatic, Analogous, Complementary, Split Complementary, Triadic or Tetradic when you need a specific relationship between hues.
- Start from a color (optional). Paste any HEX, RGB or HSL value — like
#3B82F6— and every generated color will relate to it. - Lock and customize. Press the padlock to keep a color, click Edit to fine-tune a swatch, or jump straight to its 50–950 shade ramp.
- Check accessibility. Open the Contrast Checker tab and test text against your background for WCAG AA and AAA.
- Preview, save and export. See the palette on a live mockup, save it to your browser, share it with a link, or export CSS variables, design tokens, PNG, SVG or JSON.
Tips for better prompts
- Name concrete things, not abstractions: “espresso bar in Copenhagen” beats “nice and warm”.
- Stack a color with a mood: “muted forest”, “vibrant coral”, “pastel lavender”.
- Add a context to steer neutrals: “corporate fintech blue”, “wedding blush”, “desert canyon”.
- If you already have a brand color, put it in Start from a color and let harmony do the rest.
Color harmony modes, explained
Monochromatic
One hue, several lightness and saturation levels. The safest choice for interfaces — nothing can clash because everything shares the same hue.
Analogous
Hue neighbors about 30° apart, like violet next to fuchsia. Comfortable and natural, ideal for lifestyle, wellness and editorial designs.
Complementary
Two hues 180° apart on the color wheel. Maximum tension and contrast — perfect when you need one color to pop, like a CTA on a calm background.
Split complementary
A base hue plus the two neighbors of its complement. You keep most of the contrast with less vibration, which makes it easier to balance.
Triadic
Three hues evenly spaced at 120°. Playful and colorful; let one hue dominate and use the other two as support.
Tetradic
Two complementary pairs, forming a rectangle on the wheel. The richest scheme — and the hardest. The generator keeps saturation in check so it stays usable.

From palette to production
Every palette here is a starting point for real work. Copy values in the format you need — HEX for handoff, RGB for shadows and overlays, HSL for building shades — or export the whole set: CSS variables and design tokens for developers, PNG and SVG boards for presentations, JSON for design pipelines.

Tool FAQ
How do I describe the colors I want?
Write the mood, objects or materials you imagine — for example “modern luxury skincare brand with beige, warm brown and elegant gold colors” or simply “ocean blue”. The generator reads your words in the browser and maps them to matching hues, saturation and lightness.
Does the generator send my prompt or images to a server?
No. Everything runs locally in your browser: prompts are interpreted on your device with a built-in color dictionary, and images are analyzed with canvas without ever being uploaded.
How do locked colors work?
Press the padlock on a swatch to pin it. When you generate a new palette, locked colors stay exactly the same while every unlocked swatch is regenerated.
Can I share my palette with someone?
Yes. Press Share to copy a link like /tool/?colors=6366F1-8B5CF6-EC4899. When anyone opens it, the exact palette loads instantly — no account needed.
