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.

- 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
- 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.
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 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 Adobe ASE files you can open directly in Photoshop or Illustrator, plus Tailwind/SCSS/CSS variable files for developers.
