The blue theme is great, but I’m sure there are a lot of people who like the black/dark gray theme as well. I hope to get it!

@shomnipotence ,

These are the options:

• Color Theme (COLORTHEME) in AutoCAD
• To Change the Background and Other Color Settings
• How to change the canvas background color in AutoCAD

You can also tell Autodesk what you think about their products and any improvements you would like to see:

• Product feedback

The existing UI dark theme is blue, I want a black (saturation 0)
