URL Color Border

About

URL Color Border is a lightweight Chrome extension that helps you visually identify and distinguish websites at a glance. Set custom colors for specific base URLs, and whenever you visit those sites, the extension displays subtle visual indicators including:

Colored Top Bar: A thin 5-pixel bar fixed at the very top of your browser window that stays visible even when scrolling
Badge Indicator: A colored dot on the extension icon in your toolbar showing the current site's assigned color
