Active window color changing

[jemag]

Currently the active window becomes darker when selected. For example, the Text Editor background will go darker once you click inside it (as is shown in the MoonRise official screenshots), same thing for the Package Explorer, etc.

I know this behaviour is intended, however I find that it makes the Text Editor become too dark for me and the colour when the window is inactive is just perfect.

Is there any way to change the moonrise CSS file so that the active window doesn't change colour OR changes to the same colour as when it was inactive?
