GCP Project Colorizer is a Chrome extension designed to enhance the Google Cloud Platform Console experience by allowing users to customize the banner background color based on the active project ID. This tool is particularly useful for teams managing multiple GCP projects, as it enables quick identification of the current project through distinct banner colors. Users can map specific project IDs to chosen colors, ensuring a visually organized workspace.

The extension features an intuitive popup interface for managing color rules, allowing users to easily input project IDs and select corresponding colors. Once set, the color changes are applied automatically when switching projects, providing real-time updates without the need for page reloads. This functionality streamlines project management and enhances overall productivity within the GCP Console.
