#! /usr/bin/env python """Pynche: The PYthon Natural Color and Hue Editor. Pynche is based largely on a similar color editor I wrote years ago for the Sunview window system. That editor was called ICE: the Interactive Color Editor. I'd always wanted to port the editor to X but didn't feel like hacking X and C code to do it. Fast forward many years, to where Python + Tkinter provides such a nice programming environment, with enough power, that I finally buckled down and implemented it. I changed the name because these days, too many other systems have the acronym `ICE'. This program currently requires Python 1.5 with Tkinter. It has only been tested on Solaris 2.6. Feedback is greatly appreciated.
