BabelZilla is a great project that helps translate extensions by connecting between extension developers and translators and providing convenient tools (Web Translation System - WTS) for creating, managing, and updating translations.
You are invited to register as a translator on BabelZilla and add your translation or update the missing strings in your language. Here's a direct link to the ColorZilla topic on BabelZilla.
