I thought there was an enhancement request already open for this but I could not find it. 

In IDEs like Visual Studio, Eclipse, etc. the user can set the default background color/ foreground color to something other than white.  This allows the user to set the default theme to make it easier on their eyes.  I've attached some screen shots from Visual Studio Code for an example.

"I'm a recent user of Aqua Data Studio. I noticed that there is no way to configure the color of the background of the screen. Many people have problems with plain white background if looking at it for extended periods of time. Would you be able to add some way of adjusting the color in a future release? Thanks! "
