How to generate a color palette from an image

Click the From Image tab and drop any JPEG, PNG, WebP, or GIF file into the upload area. The image color palette generator draws your file onto an HTML canvas, reads every pixel, and groups similar colors using a frequency-based quantization algorithm. It then picks the 5 most visually distinct colors and sets them as your palette. The process takes under a second for any typical photo.

This picture color palette generator works well for product photography, illustrations, movie stills, and brand screenshots. If you want to match a website or app to the feel of a photo, upload it and export the resulting palette as CSS variables or a Tailwind config block. You can also lock any extracted color and use the tints and shades generator to build a full 11-step scale from it.

How to generate a color palette from a color or HEX code

Switch to the From Color tab, enter any valid HEX code, or open the color picker to choose a starting hue visually. Select a harmony mode and click Generate. The tool calculates color relationships using HSL math and produces a balanced 5-color set. Click Generate again to get controlled random variations of the same harmony. Lock any swatch you want to keep, and only the unlocked colors will change on the next click.

If you already have a brand primary and need supporting colors, enter that primary as the base and try the split-complementary or analogous modes first. For bolder contrast, complementary or triadic modes produce more dynamic results. Once you settle on a palette, use the contrast checker to confirm every text-background pair meets WCAG 2.1 accessibility standards.

Understanding the five color harmony modes

Each harmony mode produces a different relationship between the 5 colors in your palette:

• Analogous picks colors that sit next to each other on the color wheel (30 and 60 degrees apart). The result is soft, natural, and easy on the eye. Good for backgrounds, editorial layouts, and lifestyle brands.
• Complementary pairs your base color with its opposite on the wheel (180 degrees). High contrast and visually energetic. Suited to calls to action, marketing materials, and sport or tech brands.
• Triadic takes three colors evenly spaced at 120 degrees. Vibrant and balanced. Works for children's products, creative agencies, and colorful UI designs.
• Split-complementary uses the base color and the two colors on either side of its complement (150 and 210 degrees). Less tension than pure complementary, more variety than analogous. A reliable choice for most UI projects.
• Monochromatic varies only lightness and saturation within a single hue. Produces the most cohesive and minimal output. Ideal for dark-mode UIs, luxury brands, and data visualization.

For deeper control over a single hue across many steps, the tints and shades generator produces an 11-step scale from 50 to 950 that matches Tailwind naming exactly.

Extracting a palette from a photo vs. generating from a color

A color palette from image extraction gives you colors that are grounded in a real visual reference. If a client hands you a photo of their storefront, product, or campaign imagery, extracting the palette from that image ensures your design work stays true to what they already have. The extracted colors will not always be perfectly balanced in saturation or lightness, so you may want to refine individual swatches after extraction.

Generating from a color using harmony rules produces mathematically balanced palettes that are optimized for contrast and visual coherence. These are better for projects starting from scratch where you have a single brand color and need the rest of the system built around it. Use the color format converter if you need to translate any swatch between HEX, RGB, HSL, or OKLCH before passing it to your design tool or codebase.

Using your palette in a design system or codebase

The CSS variables export gives you a :root block with five named properties: --color-primary, --color-secondary, --color-accent, --color-neutral, and --color-surface. Paste these into your global stylesheet and reference them anywhere with the var() function. Updating a palette later only requires changing the five root values.

The Tailwind export formats each color for use in a tailwind.config.js extend.colors block. Each color gets a semantic label so you can write classes like bg-primary or text-accent throughout your templates. If you need each color expanded into a full tints-and-shades scale, pass each HEX value through the tints and shades generator to get Tailwind 50-950 keys that slot directly into the same config file.

For teams working in Figma or Sketch, copy the HEX or RGB values and add them as color styles or variables in your design file. Naming them with the same labels (primary, secondary, accent) as your code output keeps the design-to-development handoff consistent. Run the final palette through the WCAG contrast checker before finalizing to confirm text colors pass the 4.5:1 ratio for normal text and 3:1 for large text.

Tips for building a strong 5-color palette

A well-structured 5-color palette for a web project typically covers five roles: a dominant neutral for backgrounds and surfaces, a strong primary for key actions and brand elements, a secondary color for supporting sections, an accent for highlights and labels, and a state color for feedback like success or warning. Assigning each swatch a role rather than using colors interchangeably gives your designs more visual discipline.

When generating a palette from a picture, nature photographs and architecture photos tend to produce more muted and balanced palettes than graphic design images. Product photography on white backgrounds often yields very limited color variety. For those cases, switch to the From Color mode, pick the dominant product color as your base, and choose an analogous or split-complementary harmony to fill out the set.

If your project needs more than 5 colors, you can generate multiple palettes with different bases and combine them, or expand individual swatches into full scales. The color scheme generator offers additional harmony types including tetradic and square schemes for projects that need a wider color range.
