When specifying colors for use in a software user interface, what's the best way to ensure that those colors will look acceptable on all common display technologies: CRT, LCD, and in particular projectors?
This topic comes up frequently during design reviews, where a work-in-progress piece of software is presented to an internal audience, and the initial reaction is "the color of that widget looks weird." The presenter then responds with "it looks fine on my laptop!"
Note that I'm not just concerned with the one or two projectors in our meeting rooms at the office, but projectors in general, as the colors also need to look acceptable when demoed in a sales presentation.
The software is a Java applet embedded in a website, if that matters. I believe our UI designers use Adobe Illustrator for most of their work.
Update: I'm not looking for 100% accurate color reproduction of the sort that motivates a full color managed workflow. I just want it to look "close enough" for lay people.
