Ok all,
Darke ask me during a chat for a color blindness resource, well this link
http://www.vischeck.com/vischeck/vischeckImage.php
will allow you to understand the impact of your graphics/colors on ppl that have various color blindness issues.
The sight will allow you to run your images through a couple different test and show the results.
Wow! Very cool link, and great that you can import your own image file to run a test on.
Now if only some of the major manufacturers would run their game images through this before publishing colorblind-unfriendly games!
BTW: Interesting Freudian interchange of the word "site" with the word "sight."
