About Contrastly
Hi there!
Tailwind Colors Contrast Checker (nicknamed Contrastly) is a little tool I built because I often found myself jumping between Tailwind docs, hex converters, and contrast checkers. All of those tools are super helpful on their own — but I wanted something that brought them together in one place, simple and friendly, with accessibility at its core.
I made it not just for myself, but for anyone who cares about making the web a little easier to read. Whether you’re a designer, a frontend dev, or just someone curious about colors, I hope it makes your workflow smoother.
Why I Made This
Sometimes I’d copy a Tailwind color, paste it into a hex converter, then paste it again into a contrast checker… only to forget which color I was testing and go back to the docs. It worked, but it felt clunky.
So instead of juggling tabs, I thought: why not have a tool that connects these steps directly? That’s how Contrastly was born — out of curiosity, a desire to save time, and the hope that it could be handy for others too.
Along the way, I put extra care into accessibility and performance. Every page scores 100 across all Lighthouse categories (including Accessibility and Best Practices), and I tested it with real assistive tech so it works for more people, not just in theory.
Who It’s For
- Designers checking color accessibility in real projects
- Frontend developers working with Tailwind
- Anyone learning about WCAG and inclusive design
What Makes Contrastly Different
- Tailwind palettes included by default
- Copy buttons and hex input for quick iteration
- Real-time WCAG AA / AAA checks
- Built-in accessibility support (keyboard navigation, reduced motion, screen reader-friendly)

Who’s Behind It

I’m Yoko, a frontend developer passionate about accessibility and thoughtful design. I love building small tools that make everyday work feel a little lighter — like this one, or Promotee (opens in a new tab), an app for practicing interview answers out loud.
When I’m not coding, I’m usually writing about accessibility and design on Medium, or sharing thoughts (and experiments!) over on X (opens in a new tab).
