So, if you look at the "features" spoiler on the main post, you'll find your answer. But I'll summarize here:
Red means, this choice is counterproductive to your current story path, so don't choose it.
Green means, this choice helps the story path you're currently on, so choose this first above all others if you want to keep doing what you've been doing.
Yellow means, this choice will lead you to story events that you haven't unlocked yet, but not ones directly applicable to your current story path, so only choose these if you just want to open some new scene you haven't seen yet just to see it or something.
I forgot what blue means, but check the original post on the first page and look under the features spoiler, bro
