Does anyone else have a 'Color-Coding' obsession for lyrics?

I was looking at my lyric sheet today and realized it looks like a rainbow. lol.

Blue for breath marks, Red for high notes, and Yellow for "facial expressions" (like 'smirk here' or 'look sad'). I feel like I can't sing properly if my paper isn't organized like this. It’s like my brain needs a map! Do u guys have your own marking system? Or do u just memorize everything by heart?
