KColor review
A free, highly flexible palette generator with accessibility checks and developer-ready exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
KColor is a browser-based color palette and design tool for developers, designers, and creators. It generates palettes from base colors, natural-language prompts, uploaded images, and Google image results. Users can also create tints, shades, gradients, monochrome palettes, and color-theory palettes. The product is fully free and available through the web, a Chrome extension, and an API, making it a strong fit for developers who want flexible palette generation without a paid tier.
Its standout strength is the depth of its color workflow. KColor combines WCAG and APCA contrast checks with color-vision deficiency simulation and previews in website and app layouts. That gives users several ways to review a palette before exporting it. Palette management includes saving, pinning, sharing, and browsing, while image extraction supports a direct path from visual references to usable color systems. For developers, Tailwind palette generation adds a focused route from exploration to implementation.
KColor also fits a broad design and development ecosystem. Exports cover SCSS, CSS, Tailwind, Bootstrap, Radix, JSON, CSV, PNG, SVG, ASE, Hex, OKLCH, HSL, RGB, and Display-P3. Integrations include Tailwind, Bootstrap, Radix, Figma, and Claude. That breadth suits teams moving palettes between code, design, and image workflows. It may be more than needed for someone who only wants a quick, manually selected palette, but developers needing generation methods, accessibility review, previews, saved palettes, API access, and multiple export paths should find the feature set well aligned.

- Combines WCAG, APCA, and color-vision deficiency checks
- Exports to code, design tools, and image formats, including Tailwind
- Where it doesn't
- Its broad generation toolkit may exceed the needs of simple palette picking

- Preview and accessibility tools still leave final color decisions to the user
