Good question John! Thanks for mentioning this! I have NOT encountered such software which enabled color-blind persons to see different colors properly, but I personally found that I have to help people to replace very dark Blue to Turquoise on their 3270 Emulators. Certain CRT monitors can't display dark blue properly under fluorescent tubes.
On very old monochrome monitors, I have to replace red with something else, they're only visible when you turned contrast and brightness all the way up...

Any sort of displays used with a z/OS machine. Trad 3270, consoles, HMC, etc. Good emulators like PCOMM, BlueZone, Vista, etc are all capable to support color-blind persons by way of customizing fonts (type and size) and color. You really need a person with 'normal' eyesight to help with the changing of on-screen color. I'm not sure about Web browsers since they're not easily customizable due to dynamic nature of content. For protanope- and deuteranope-afflicted, tests must be done to see how they perceive colors like RED and GREEN on different media like paper, screen, paint, etc. Adjustments can then be done. There are software available for users to switch a color filter on and off choosing from a set of possible color transformations that will displace the colors in order to disambiguate them. HTH!
