What you can use a palette for

Brand color systems

Drop your inspiration board, get a 4-color brand palette. Brand-friendly mode picks the 3 most-distinct hues + a neutral. Export as Tailwind config for your design system.

Web / app design

Match your site to a hero image, restyle a landing page, build a dark-mode variant. Accessible mode flags WCAG-AA-compliant text/background pairs. Export as CSS variables drops straight into your :root.

Painting / illustration reference

Extract palettes from a master painting (Monet, Van Gogh, Hopper) to study their color choices. Use as a reference palette for your own digital painting in Procreate / Photoshop.

Interior / fashion mood boards

Photograph a room you love or save a Pinterest fashion shot, extract the palette, take HEX codes to a paint store / fabric shop. Muted mode is best for interior design (avoids loud accent colors).

Presentations / decks

Extract palette from your hero deck image, apply across all slides for visual cohesion. Brand-friendly mode keeps it to 3 hues — the rule for non-distracting presentations.

Album / book cover analysis

Reverse-engineer iconic album / book / movie-poster palettes (Dark Side of the Moon prism, Penguin Classic spines, Wes Anderson stills). Great for design-history study and parody projects.

AI Color Palette Generator — FAQ

Drop any image, get a structured 4-10 color palette back. 5 extraction modes (Dominant for overall mood, Vibrant for eye-catching highlights, Muted / pastel for soft tones, Brand-friendly for 3 distinct hues + neutral, Accessible for WCAG-AA contrast pairs). Output as HEX / RGB / HSL / all formats. One-click export to CSS variables, Tailwind config.

Coolors ($3-12/mo Pro for image-to-palette + saving) is the closest direct competitor — same workflow, paid. Adobe Color (free but bundled with $22.99/mo Photoshop plan for serious use) has the gold-standard accessibility checker. Khroma (free + $4.99 Pro) is text-to-palette only — no image extraction. Free.ai matches Coolors' image extraction + Adobe's WCAG check, $0, no signup.

Dominant for design inspiration / mood-board summary (most-frequent colors). Vibrant for hero elements + CTAs (eye-catching peaks, ignores grays). Muted for interior / fashion / wellness (skips loud accents). Brand-friendly when you need 3 hues you can actually use as primary + secondary + accent. Accessible when building a UI palette where text needs to pass WCAG-AA on backgrounds.

HEX (#FF5733) for general use. RGB (255, 87, 51) for design tools. HSL (12, 100%, 60%) for tweaking lightness / saturation. "All formats" lists every conversion side-by-side. One-click export buttons: copy all HEX as plain text, CSS variables block (:root { --color-1: #FF5733; ... }), or Tailwind config (theme: { extend: { colors: { ... }}}).

Yes — drop your hero photo, pick Brand-friendly mode, get the 3 most-distinct hues + a neutral. Apply that palette site-wide via CSS variables. AI Color Palette Generator returns colors in order of dominance, so the first 3 are typically your primary / secondary / accent and the rest are tones you can use sparingly.

Yes — pick Accessible mode and AI Color Palette Generator flags HEX pairs that pass WCAG-AA contrast (4.5:1 for normal text, 3:1 for large text). Black / white pairings against each color are noted. For full UI accessibility audit, also check WebAIM Contrast Checker and your design-system docs.

4 for logos / icons / product packaging (limited palette = strong brand). 5-6 for landing pages / marketing sites (default sweet spot). 8-10 for full design systems with primary / secondary / tertiary / utility / state colors. Going above 10 causes decision paralysis and visual chaos — restrict by combining tones you would not use anyway.

Photographs, paintings, posters, screenshots, mood-board collages — anything with distinct color regions. JPG / PNG / WebP up to 10MB. Solid-color images (single-color background) extract trivially; busy mixed-content images get more interesting palette data. Higher-contrast inputs produce more useful palettes.

Yes — extract palette from any of our /image/generate/ outputs to maintain visual consistency across a series. Generate a hero image, extract its palette, use the palette as the design system for the rest of your project.

Yes — copyright applies to the image itself, not to the abstract idea of "the colors used in this image". Extract the Dark Side of the Moon prism, Wes Anderson stills, Mondrian primaries, Hopper interiors. Use the palette in your own original work; do not reproduce the source image.

No — your uploaded image is processed and discarded immediately. We log only the anonymized palette result for analytics + your own /account/?tab=history. Privacy policy at /privacy/.

Yes — POST multipart to /v1/image/colors/ with image file, num_colors (4-10), mode (dominant / vibrant / muted / brand / accessible), format (hex / rgb / hsl / all). Bearer auth, 10K tokens/month free. /api/ has the curl example.
