## Description

**URLColors** is a handy Chrome extension designed for developers and users who navigate multiple web environments. It adds a customizable colored border around websites that match user-specified keywords in their URLs. This feature is invaluable for distinguishing between development, testing, and production environments, preventing costly mistakes on live sites.

Users can personalize their experience by setting border color, width, opacity, and even enable blinking borders with adjustable intervals. The extension also offers a demo or snooze mode, temporarily disabling borders during presentations and automatically reactivating afterward. Open-source and community-driven, URLColors invites contributions via its [GitHub repository](https://github.com/fej-snikduj/URLColors/). Developed collaboratively by @dzoba and others, this extension enhances workflow clarity and safety for web developers.
