No

I think the color coding were that green meant likes, and red meant dislikes

Likes where blue right?

Yep

Na

I think likes in Shorts still appear blue, plus they have a small animation/sprite thing when you tap on them.

Back in the early 2010s, likes were green while dislikes were red

2013 also? because i dont remember that

I don’t remember the exact years

Yeah they were green and red
