I didn't even realize that the red/green was present until you mentioned it!
I do actually perceive it, now that you draw attention to its existence, and can tell the difference, but you are correct: thin lines are aggravating to deal with!
And it's not just the red/green issue: it's also in distinguishing them from grey when the lines are thin.
Side issue: when I was a kid, my math teacher insisted on grading using those thin BIC red pens. The problem is that it was indistinguishable from my own writing (at a glance), and it took forever to find my mistakes that were "clearly marked" by the teacher. Thin red lines are pointless to me. I guess it's a good thing that I'm naturally good at math!
