Color Palette Generator
A color palette generator is a tool that produces a set of harmonized colors for design and development work. PhotoTones is an image-driven color palette generator — upload any photo and get a ready-to-use palette with hex, RGB, and HSL codes in under a second.
The Two Kinds of Color Palette Generators
Most tools fall into one of two buckets:
1. Image-driven generators (PhotoTones)
You provide a reference image — a photo, logo, or artwork — and the tool extracts its dominant colors. Best when you already have a visual direction you want the palette to match.
2. Rule-based generators (Coolors, Adobe Color)
You pick one color and the tool uses color theory rules (complementary, triadic, analogous) to suggest harmonious siblings. Best when you're starting from a single brand color or a mood.
PhotoTones focuses on the image-driven approach because it produces palettes that feel grounded in real-world imagery — the kind of palette a photo shoot or art director would actually produce.
Generate palettes from real photos
Not random swatches — colors from your image. Pro ships a full brand kit from one click.
What a Good Palette Generator Returns
- Hex, RGB, and HSL codes for each color — three formats because different tools accept different inputs
- Named categories (Vibrant, Dark Vibrant, Light Vibrant, Muted, Dark Muted, Light Muted) so you can map each color to a role in a design system
- One-click copy for individual colors and bulk copy for the whole palette
- Variation presets so you can regenerate the palette for a different emphasis without re-uploading
- Downloadable composite — the original photo with the swatches attached, ideal for mood boards
- Professional exports (Pro) — Adobe ASE, Tailwind config, SCSS variables, CSS custom properties, Procreate swatches
- Design deliverables (Pro) — brand kit ZIP, W3C/Tokens Studio design tokens, Figma import JSON, light/dark theme CSS
- Accessibility info (Pro) — WCAG contrast grid with AA/AAA pass/fail badges
How to Choose a Color Palette Generator
- Privacy. Does the tool upload your image? PhotoTones processes everything in the browser; images never leave your device. Most competitors upload.
- Export formats. If you work in Tailwind, SCSS, or Procreate, pick a generator that exports native formats rather than forcing you to copy hex codes manually.
- Palette size. 6 colors is a minimum. Professional design systems need 8–12. PhotoTones Pro supports up to 12.
- Accessibility. Look for WCAG contrast checking baked in so you don't publish inaccessible color combinations.
- Pricing. Free tools should cover 80% of cases. Paid features should be clearly professional — exports, extended palettes, accessibility — not paywalled basics.

PhotoTones is free forever — extract 6 colors per image with hex, RGB, and HSL copy, plus a 50% resolution composite JPEG download. No signup required. PhotoTones Pro ($7/month, cancel anytime) extends palettes to 8, 10, or 12 colors, full-resolution downloads, brand kit ZIP, design tokens, Figma JSON, and professional exports (Adobe ASE, Tailwind, SCSS, CSS).
FAQ
What is the best free color palette generator?
The best free color palette generator depends on your workflow. For image-driven generation, PhotoTones is the fastest, most private option. For rule-based generation from a single seed color, Coolors and Adobe Color are strong choices. PhotoTones stands out for keeping everything local in your browser.
How many colors should a palette have?
Most brand palettes use 4–6 colors. Design systems typically expand to 8–12 to accommodate semantic roles (primary, secondary, success, warning, error, neutrals). PhotoTones supports 6 by default, up to 12 on PhotoTones Pro.
Can I save and share a generated palette?
Yes. Click "Download photo with color swatches" to get a shareable composite image. PhotoTones Pro also exports a brand kit ZIP, design tokens, Figma JSON, light/dark theme CSS, Adobe ASE, Tailwind/SCSS/CSS files, and Procreate swatches.
Can PhotoTones generate palettes without an image?
PhotoTones is image-driven — upload a photo, logo, or artwork to extract its dominant colors. For rule-based palettes from a single seed color (complementary, triadic), tools like Coolors or Adobe Color are a better fit.
