Tools to assist colorblindness

["Peter A. Bonucci" <peter.bonucci@verizon.net>]

I'm looking for color naming software that will run under KDE.  When I used 
Windows, I used WhatColor ( http://www.hikarun.com/e/ ).  It would put a 
label on the screen with the name of the color under the cursor.

With all of the color coding people are using now, I'm too colorblind to 
effectively use many computer programs without this.

Is there anything like this under Linux?

If nothing like this already exists, is there a standard method for reading 
screen pixel colors?  I'm willing to write this, but I have no experience 
writing KDE applications or interfacing to KDE like this.  If someone could 
point me to the proper documentation, I would appreciate it.
