I use dark mode in my text editor and on my smartphone, and switching between the dark screen of the text editor and the bright screen of the management console is a bit disconcerting. However, I am glad to see that dark mode is now available in the AWS management console as well.
Steps to Change to Dark mode
Step 1: Open Settings
Step 2: click "Edit" on Display
Step 3: Select dark from visual mode and save settings

Dark mode is not yet available for all services, including IAM.
The dark mode does not strain your eyes, so you can work for long periods of time.
hope this blog is helpful.
