Subject: function to get inverse color name?
Date: Wed, 23 Apr 2014 20:03:04 -0700 (PDT)	[thread overview]
Message-ID: <2c7e7b5b-73ec-45ae-9bf5-b638aad861ff@googlegroups.com> (raw)

Hi all.

I'm doing a major overhaul of my emacs 24 init.el files.  I'm trying to convert a lot of faces from dark to light to set up alternate themes.  I know I can just invert everything with invert-all-faces, but I want to do them individually and have the correct name.

Does anyone have a function that takes a named color (e.g. "Red") and returns the inverse?  I guess it would convert the name to RRGGBB, subtract each 8-bit value from 256, and then convert back to a name.

Thanks for any help and/or pointers to useful functions!

 David
