Changing Background Color in Rstudio
It's simple now.
Tools > Options > Appearance
Choose color.
That's it.
It isn't, but if you're running Linux, you can have the window manager invert the color of just one window. Target this to the RStudio window and you'll get RStudio with an inverse theme. (This was a common trick employed with Eclipse until it got a dark theme with the release of Eclipse Luna.)

Hi all
since this is work in progress and i don't want to update this post all the time i moved the project to GitHub. Fell free to download the files from there.
The issues with dropdown menu, autocomplete and popups are solved in the latest Version on GitHub. Still newer builds than version 1.0.143 are not supported. But i will work on it.
Edit (05.05.2017): My custom_style.css works with the actual stable Version of RStudio 1.0.143 . Newer Preview and Daily Builds got already an upgrade where you can choose out of 3 different Themes. My files don't work with these newer builds at the moment, but I am working on it. Cause only one of these themes is kind of a dark metal blue but not the dark them i want to have. I will upload it as soon as it works.
I tested my theme yesterday on a Lubuntu 17.04 OS. Here are the Install instructions for Linux: Enter your installation folder for rstudio
cd /usr/lib/rstudio
Copy the Dark Theme folder you downloaded to the rstudio install dir
sudo cp -avrf /home/<user>/Downloads/RStudioDarkStyle ./
First save the Original files to a new folder (vanilla) if something goes wrong
sudo mkdir vanilla
sudo cp -avrf ./www/index.htm ./vanilla/index.htm
sudo cp -avrf ./resources/R.css ./vanilla/R.css
sudo cp -avrf ./resources/grid/gridstyles.css ./vanilla/gridstyles.css
If you set own styles before you can also save them if u don't have this may result in an error.
sudo cp -avrf ./www/custom_styles.css ./vanilla/custom_styles.css
Then we replace the original files with the new ones
sudo cp -avrf ./RStudioDarkStyle/index.htm ./www/index.htm
sudo cp -avrf ./RStudioDarkStyle/custom_styles.css ./www/custom_styles.css
sudo cp -avrf ./RStudioDarkStyle/R.css ./resources/R.css
sudo cp -avrf ./RStudioDarkStyle/gridstyles.css ./resources/grid/gridstyles.css
And thats all it should work now.
I found this guide how to make rstudio dark by zencoder on rstudio support
and improved it a little bit.
I edited the custom_styles.css and the gridstyles.css the other files are original as zencoder wrote them.
For Installation guide see the readme file. I use the "Vibrant Ink" Apperance with it on a Win7 pc.
I didn't even try to change the plot window, because most graphics are used in papers and such and are normaly printed with a white background, for me it is more functional to have a white background for plots.
Have fun with this hope it helps.
