AWS Colours is a free Chrome extension developed by Gingerbreadmat that allows users to customize the header color of the AWS console based on the selected Region and/or Account. By default, each Region is assigned a specific color, but with this extension, users can choose any CSS color for both the Region and/or Account.

This extension aims to prevent resources from being mistakenly created in the wrong Region and/or Account by providing a clear visual indication of the currently selected settings. With AWS Colours, users can easily differentiate between different Regions and Accounts, reducing the risk of errors and improving overall productivity.

Overall, AWS Colours is a useful tool for AWS console users who want to customize their experience and ensure they are working in the correct environment. It provides a simple and effective way to visually distinguish between different Regions and Accounts, minimizing the chances of making mistakes.
