Thanks for the response! I don't know what engine this game is using, but if it isn't custom, it may be worth looking into what accessibility features it supports out of the box, to make things easier on you.
Keyboard support and color blind access are both great. However, until you do have full blind support, I would suggest that you use the color blind tag rather than the blind support tag. It may seem like a small difference, but to those of us in the blind community, it means a very different thing. I can't blame you for not knowing that though... :)
I've been watching Star Trek since I was a kid, so it's great to hear that you are interested in adding more accessibility support. You could try r/blind on reddit or the audiogames.net forum for advice on how to add it.
