CVAT new UI: background color

[aschernov]

My actions before raising this issue

• Read/searched the docs
• Searched past issues

Expected Behaviour

An opportunity to change the background color

Current Behaviour

The background color ( the area behind the work space) is only white. We have the opinion that it's not good for eyes, especially during long annotation:

Possible Solution

Develop several neutral background colors and create a corresponding setting to choose the one of them.

Context

Visual settings are also very important when we deal with long work in the annotation tool.
