Just looking at it brings me a smile of great color justice!
Mario games have also had a good track record of vibrant colors, and Nintendo in general, really. I miss the old days when they only had a limited amount of colors to work with and no one cared what "mauve" was.
Hopefully more (see: most) games in the future will include this option if possible. I can't see it being that much trouble, seeing as how it's just a couple color switches. Luckily, someone long ago decided that if two unnamed teams are going against each other, one is the Red team and the other is the Blue team, as seen in Team Fortress 2, 3v3 Arcade Hockey, and Supersonic Acrobatic Rocket-Powered Battle-Cars (all of which I play a bunch). All developers should adopt the tagline: "No rods, No cones, No problem!"
[Yes I realize that colorblindness doesn't mean we have NO cones/rods, but it makes for a catchier tagline, damnit!]
