Color tools online for every stage of design
Color decision-making starts at the beginning of a design project and carries through to the final line of CSS. Start with palette generation to establish primary, secondary, and accent colors. Use the tints and shades generator to build a complete 11-step scale for each base color. Run the WCAG contrast checker to confirm that every foreground and background combination meets AA or AAA requirements before your design reaches production.
The color scheme generator covers complementary, analogous, triadic, split-complementary, tetradic, and monochromatic relationships. The image color picker extracts a dominant palette from any photo. The color name finder maps any HEX value to the nearest named CSS color.
Color picker from image and color extraction tools
The most-used tool on this page for designers working from visual references is the image color picker. Upload any photo and the color extractor identifies the dominant hues using pixel frequency analysis and perceptual distance filtering. Each extracted color comes with its HEX, RGB, and HSL code ready to copy. All image processing runs in your browser. The photo is never sent to a server.
To go from a photo to a complete design system: extract colors from the image, take the most prominent HEX, and feed it into the color palette generator to build a 5-color harmony palette, or into the scheme generator to apply color theory relationships. Use the tints and shades generator to build a 50–950 scale for each hue. This workflow takes you from a single image to a production-ready token system.
Color converter tools and color code finders
The color converter tool handles every standard CSS format: HEX, RGB, RGBA, HSL, HSLA, and OKLCH. Enter any value in any format and the tool converts it to all other formats simultaneously. This is useful for translating design tool output (usually HEX) into CSS custom properties or HSL values for dynamic color manipulation.
The color name finder works the other way: enter a HEX value and it identifies the closest CSS named color using Delta-E perceptual distance. Useful for finding readable color names for documentation, prototyping with named values instead of hex codes, or understanding what named color your brand HEX is closest to. The full list of 140 CSS and HTML named colors is browsable and searchable in the tool.
CSS gradient and shadow generators
The CSS gradient generator builds linear, radial, and text gradients with live preview. Add as many color stops as needed, adjust direction and position, and copy the complete CSS declaration. Tailwind export is included for gradient utility class output.
The CSS box shadow generator gives you interactive controls for offset, blur, spread, color, and inset mode. Layer multiple shadows, preview them against a live card, and copy the complete box-shadow value. Preset styles covering soft UI, material elevation, neon glow, and focus rings are available as starting points.
CSS output and developer-ready export
All nine free color tools produce CSS-ready output. The palette generator exports CSS custom properties. The gradient maker generates the complete background declaration. The color format converter produces HEX, RGB, RGBA, HSL, and CSS variable output simultaneously. The tints and shades generator outputs a complete Tailwind-compatible color object. Results update in real time as you adjust inputs, and every tool includes a one-click copy button for the output.
For image-based workflows, the hex color picker from image returns values that paste directly into any design tool or CSS file. The image to color code pipeline (upload, extract, copy HEX) takes under ten seconds and produces values compatible with Figma, Sketch, Adobe XD, VS Code, and any browser DevTools color picker.
Frequently asked questions
Upload your image to the color picker from image tool on this page. The tool analyzes pixel data using the Canvas API and extracts the dominant colors automatically, returning each one with its HEX, RGB, and HSL values. All processing happens in your browser. No image is uploaded to any server.
Use the image color picker tool. Upload any JPEG, PNG, or WebP photo and the tool identifies the most dominant colors and displays their HEX codes directly. Click any swatch to copy the HEX code to your clipboard. For a single pixel, use your browser's built-in DevTools eyedropper for pixel-level precision.
The color extractor from image tool accepts any browser-supported image format. After uploading, the algorithm scales the image, builds a pixel frequency map using color quantization, and returns the most visually distinct dominant colors with their HEX, RGB, and HSL values. You can then export the palette as CSS custom properties.
Upload your image to the color picker from image tool to extract the dominant colors. Then take the most prominent extracted HEX and enter it into the color palette generator to build a full 5-color harmony palette based on color theory, or into the color scheme generator for complementary, analogous, and triadic variations.
Yes. All color tools use standard browser APIs including the Canvas API for image processing and CSS parsing for color conversion. They work in Chrome, Firefox, Safari, and Edge without any extension or plugin.
Yes. The palette generator, tints and shades generator, and gradient maker all include Tailwind-compatible output. The tints and shades tool matches Tailwind's 50–950 color scale naming convention exactly.
The contrast checker uses the WCAG 2.1 relative luminance formula exactly as defined in the specification. Results match Google Lighthouse, WebAIM Contrast Checker, and other industry-standard tools.
The right color tool depends on your starting point. If you have an image, use the color picker from image to extract dominant colors. If you have a brand hex code, use the palette generator or tints and shades generator to build a full color system from it. If you need to check accessibility, the WCAG contrast checker gives you exact ratios against the AA and AAA standards.
