How do I change the background color of aptana studio?

Question

How do I change the black background of the Aptana IDE (or the entire theme) to a different one, like blue?

Answer 1

To change the master theme do as above, but if you want to change the editor theme, go to

Window -> preferences -> aptana studio -> publishing -> themes

In Aptana 3.6.1 "editor theme" is the second option in that tree. You can use one of the built-in themes or import your own.
