Free WCAG Color Contrast Checker

What it does

A color contrast checker for designers and developers who care about accessibility. Enter two colors (text and background) and instantly see the contrast ratio, plus pass/fail status for WCAG 2.1 AA and AAA for normal and large text and UI elements. It’s fast, free and runs entirely in your browser - a small but essential helper for more inclusive, modern interfaces.

Sprawdź kontrast i czytelność kolorów według WCAG 2.1 AA i AAA. Dodaj kolory, odczytaj poziom kontrastu i użyj automatycznej korekty.

Wpisz kolor tekstu i tła a narzędzie pokaże, czy kontrast miedzy nimi jest wystarczający. Obliczenia opierają się na międzynarodowym standardzie dostępności WCAG 2.1 AA i AAA, który określa minimalne wartości kontrastu. Dzięki temu osoby z różnymi wadami wzroku mogą swobodnie korzystać z treści cyfrowych. Jeśli kontrast jest zbyt niski, funkcja Dopasuj automatycznie znajdzie wariant koloru spełniający wybrany próg. Czytelność to różnica jasności między kolorem tekstu a kolorem tła. Im większa ta różnica, tym łatwiej odczytać tekst. Zbyt niski kontrast sprawia, że treść staje się trudna do przeczytania - szczególnie dla osób z wadami wzroku, osób starszych lub w trudnych warunkach…from tools.arteonagency.pl

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  22 GB of Hacker News in SQLite▲730

  Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
