I used to do this, but I am drowning in way too many inks now to color match all the time lol

I have a notebook dedicated to scratch notes. It's chaotic but I definitely have better recall and can even remember which pages I wrote specific info on, vs using a digital method (which really makes no sense because it's so much easier to organize things digitally lol). I also have a planner for listing appointments, meetings, etc. and for my daily to-do lists. I've tried different systems, both analog and digital, but this is what works best for me.

This was one of my favorite games on the Nintendo DS!
