Free Design Utilities for Web Developers & Designers
Good design decisions often start with the right color. Whether you're building a brand identity, choosing an accessible UI palette, or experimenting with a new visual style, having fast, browser-based color tools at hand removes the friction between idea and execution. Everything here runs locally — no subscription, no export limits, no watermarks.
The Color Tools suite covers the full workflow: pick colors with a visual picker, convert between HEX, RGB, HSL, and OKLCH, check contrast ratios against WCAG AA and AAA accessibility standards, and generate complementary, analogous, triadic, and split-complementary color schemes. Accessible color choices are no longer a specialist skill — the contrast checker tells you exactly which text/background combinations pass or fail before you write a single line of CSS.
The CSS Gradient Generator creates linear and radial gradients with a live preview. Add as many color stops as you need, adjust angles and positions, and copy production-ready CSS with one click. No more wrestling with gradient syntax — the output works in every modern browser without vendor prefixes.
These tools are particularly useful during the early stages of a project — when you're building a design system, reviewing a Figma handoff for accessibility issues, or prototyping UI components. The instant feedback loop between visual change and code output speeds up iteration significantly compared to toggling between design tools and browser DevTools.
All design tools work offline once loaded. Bookmark any page and it remains available even without an internet connection — useful in conference rooms, on flights, or anywhere connectivity is limited.
