Why use Color Palette Generator
8 color-harmony schemes
Monochromatic, analogous, complementary, split-complementary, triadic, tetradic, shades, and tints — all from one base color.

Instant regeneration
Every scheme and the random-color button update the palette live, with no reload.
Per-swatch copy
Click any individual swatch to copy just that hex code.
Nothing uploaded
Palette generation and image color extraction both run locally in your browser.
Who uses Color Palette Generator
Starting a website color scheme
Generate a coordinated palette from one brand color instead of guessing complementary shades by eye.

Exploring color combinations
Use the random button and different schemes to discover palettes you wouldn't have picked manually.
Presentation and slide decks
Generate a small coordinated palette for consistent chart colors and accent highlights.
Quick client mockups

About Color Palette Generator
Picking colors that work well together is harder than picking one color you like — color theory schemes exist specifically to solve this by defining mathematical relationships between hues that reliably look coordinated. This tool implements eight of the most useful ones, each generated instantly from whatever base color you choose.
Monochromatic varies only lightness for a subtle, cohesive palette. Analogous pulls from hues next to each other on the color wheel for a harmonious feel. Complementary and split-complementary use opposite hues for high contrast and visual energy. Triadic and tetradic use three or four evenly spaced hues for vibrant, balanced palettes. Shades and tints simply mix your base color toward black or white — useful for a UI color's hover, active, and disabled states.
The image-extraction mode solves a completely different problem: starting from a photo instead of a color wheel. It samples the image's pixels, groups similar colors together, and returns the most visually dominant, distinct shades — useful for building a palette that matches a brand photo, a piece of art, or any image you want a design to feel consistent with.
Every palette can be copied as ready-to-use CSS custom properties with one click. All generation and image analysis happens directly in your browser — nothing about your base color or any photo you upload is ever sent anywhere.

| Schemes offered | 8 built in | Varies | Often 1-3 |
| Extract from a photo | Yes, built in | Varies | Sometimes a separate tool |
| CSS export | One-click, full block | N/A | Often manual copy-paste per color |
| Data privacy | Never leaves your device | N/A | Usually fine, but varies |
Pro tips
- Complementary and triadic schemes create high contrast and energy — good for accents, but often too intense for large background areas.
- Monochromatic is the safest choice for a cohesive UI, since every color shares the same hue and saturation.
- For a UI color's interactive states (hover, active, disabled), the "shades" or "tints" scheme generates a natural progression from your base color.
- The image-extraction mode works best on photos with clearly distinct color regions — a very uniform or low-contrast photo will return fewer usable colors.
- The copied CSS block uses generic --color-1, --color-2 variable names — rename them to match your project's convention after pasting.

Privacy & security
Whether you're generating from a base color or a personal photo, nothing about either needs to leave your browser to build a palette.
Palette generation uses local color-theory math — nothing is sent anywhere.
Any photo you upload for color extraction is decoded and analyzed entirely in your browser tab.
No account, email, or login required.
Nothing is stored or logged after you close the tab.
Frequently asked questions
Is this tool free to use?
Yes, completely free with no limits, and no account needed.
How is my data handled?
Palette generation and image color extraction both happen locally in your browser — no image or color is ever uploaded to a server.
What's the difference between shades and tints?
Shades mix your base color toward black (darker); tints mix it toward white (lighter) — both create a natural progression useful for UI states.
Can I generate a palette without picking a base color?
Yes — click "Random" to generate a random base color, or upload a photo to extract a palette instead of choosing a base color manually.
How many colors does each scheme generate?
It varies by scheme — complementary returns 2, split-complementary and triadic return 3, tetradic returns 4, and monochromatic, analogous, shades, and tints return 5.
Troubleshooting
The image extraction found fewer than 6 colors
This happens with photos that are visually uniform or low in color variety — the tool intentionally skips near-duplicate shades rather than padding the palette with them.
My uploaded photo isn't extracting the color I expected
Extraction is based on which colors are most frequent across the image after downsampling — a small but visually striking detail may be under-represented if it covers little of the frame.
Which scheme should I use for a website?
Monochromatic or analogous work well for most UIs; reach for complementary or triadic specifically when you want high-energy accent colors.
The CSS variable names don't match my project
The exported block uses generic --color-1 style names by design — rename them after pasting to match your project's naming convention.
