Color blind users and default color scheme

Question

Has anyone else had to support color blind users, and found that the default OBIEE color scheme (e.g. for line graphs) didn't work for them?
I was going to file an SR about this, but wanted to see what other folks were doing, if anything.

Hi Dog Lover!
Have you had any luck finding information since your original posting?
There are resources on the internet that offer those with normal color vision a glimpse at what colors a color deficient observer might perceive, but I haven't heard of any tools for doing the reverse...
The actual in-the-brain process of color sensation isn't fully understood yet, so anything that simulates what someone with color deficiency might see is an educated guess at best.
Check out www.colorhelper.com. There's a software product called the eyePilot that allows you to distinguish a single color apart from any others on a web page or other sources of visual media. I don't know how accurate it is, and I haven't tried it myself, but there's a trial version available so perhaps it could be useful.
Your best bet would be to have someone you know with normal color vision check your web pages and give you feedback on what colors work well together. You can also check color coordinate values (RGB, Lab, etc.) on images in Photoshop by using the eyedropper tool and the "INFO" information window.
Hope this helps!
