Thanks for keeping this updated. One of the guys on our team is color blind so we definitely feel your pain. I asked about this when I started and as I understand it, it is much more complicated to build an option to swap color blind mode rather than just replacing things as you do, since it has such far reaching implications over many of our assets. It's something I'd like to see done (including alternate modes for the less common blue-yellow color blindness conditions), but unfortunately it is hard to get prioritized.
In the meantime, take heart that your efforts have no gone unnoticed at Riot! You're getting my first red post, how does that feel?
