Why Colaro?
Everything you need to work with color professionally, in one place.
Free Forever
Every tool is completely free. No account, no premium tier, no usage caps. Just open and use.
WCAG Accessibility
Our contrast checker follows WCAG 2.1 AA and AAA standards to help you build inclusive interfaces.
Zero Tracking
Your color data stays in your browser. We don't collect, store, or sell anything.
Free Color Tools for Designers and Developers
Colaro is a free, web-based color utility platform built for the full spectrum of color-related workflows. Whether you're converting HEX codes for a CSS design system, checking WCAG contrast compliance for an accessible UI, generating palettes from brand inspiration, or simulating how your interface looks to color-blind users — every tool on Colaro is free, instant, and requires no account or subscription.
Tools for Every Color Workflow
Colaro's 17 tools span four core categories. Color generators — including the Color Picker, Palette Generator, Gradient Generator, and Tailwind Shade Generator — help you create and explore new color ideas from scratch or from a seed color. Converters — including HEX to RGB, HEX to HSL, RGB to HSL, and Opacity Previewer — handle the format translations every web developer makes daily. Analyzers — including the Contrast Checker, Palette Extractor, Image Color Picker, and Text Color Preview — help you evaluate and refine existing color choices against real data. And the Color Blindness Simulator ensures your designs work for users across all types of color vision.
Built for Accessibility and WCAG Compliance
Accessibility isn't an afterthought on Colaro — it's built into the platform's core. The Contrast Checker evaluates your text-background combinations against WCAG 2.1 AA (4.5:1 for normal text) and AAA (7:1) standards, giving you immediate pass/fail feedback. The Color Blindness Simulator shows how your designs appear across deuteranopia, protanopia, tritanopia, and achromatopsia. Together, these tools make it practical to bake accessibility into every design decision rather than auditing for it at the end.
Why Colaro
Unlike tools that lock features behind paywalls or require account creation, Colaro's entire tool suite is free and unrestricted. All processing happens in your browser — your images and color data never leave your device. The platform is optimized for speed, works fully on mobile, and is built to integrate naturally into existing design workflows alongside Figma, VS Code, and your browser's developer tools.
Is Colaro completely free?
Yes. Every tool on Colaro is free with no account, no usage limits, and no premium tier. All 17 tools are available immediately.
Does Colaro store my colors or images?
No. All color processing happens entirely in your browser. No data is sent to any server — your colors, images, and design work remain private.
What color formats does Colaro support?
Colaro supports HEX, RGB, RGBA, HSL, HSLA, HSV, CMYK, and oklch. Most tools output multiple formats simultaneously with one-click copy.
Can I use Colaro for WCAG accessibility auditing?
Yes. The Contrast Checker tests any color pair against WCAG 2.1 AA and AAA standards. The Color Blindness Simulator tests designs across multiple vision types. Together they cover the core color-related WCAG requirements.
