@Jordan Dobson "I don't see how being color blind would be an issue.
I believe most can still see color but just not the entire spectrum. They would just end up with a different version colors." It's not quite that simple. While most of us with colorblindness can "still see color" we perceive them differently and have varying levels of ability to distinguish one color from the next. As someone who is red-green deficient, the most common deficiency I believe, it's not just that I see a different "version" or shade of green. I also have a hard time distinguishing some reds from some greens because they appear similar to me (My wife brought two "green" peppers to me in the store. I said we needed a "red" one too. She held up the "red" one to let me know we were covered). What's more is that colors with red or green in them (purples look blue, browns can be red or green, and forget about salmon or fuchsia) can be problematic (And it's getting worse as I get older). Contrast will certainly help but doesn't that add another dimension to it? How do you explain this concept to users? If you can perceive colors do this? If you can't perceive colors do this? Given the variations in perception that are only exacerbated by other random elements such as monitors, tiny swatches (grr) and age (which effects both perception an acuity) I don't see how this model would be appropriate for something as critical as logging in.
