This page is about an entirely optional and purely cosmetic tweak to the pipeline. Feel free to ignore this page entirely. It only applies to Macs and Linux computers.
The graphics windows produced by IDL are pretty basic and dated by modern computing standards. Particularly on Macs and Linux computers running X11, GUI windows are entirely gray on gray. This is kind of boring, and bad from a user interface design standpoint, but we’re mostly stuck with it. IDL does not provide any real ability for programs to control their appearance for instance by adjusting fonts or colors. It just can’t be done from inside IDL code!
However, it is possible to slightly tweak the appearance of IDL graphics windows using an ”.Xdefaults” file in your home directory, and get slightly improvements to appearance and legibility.

If you would like this, please create a file .Xdefaults in your home directory, and paste the following text into it:
