Negate colors of a window in openbox

I have been running ubuntu for the past few months with compiz enabled, and I have really enjoyed the ability to negate the colors of any window with Super-n. It's great for readability at night.
Anyway, now that I am back on my arch machine, I am wondering if I can achieve a similar effect while running openbox?

Re: Negate colors of a window in openbox

Compositing would be required in order to negate the colors of individual windows. As xcompmgr does not support doing this, I think your only option would be compiz.

However, there is a program that I found a while ago called xcalib (in the AUR) that allows you to negate the colors of your entire display with this command:

xcalib -i -a

There may be a way to do this with the standard X tools, but I'm not aware of it.
