Guy's Behavior

If a guy remembers your eye colour, does that mean anything?

So today someone brought up eye color. I turned to my friend and asked what colour my eyes were and he told me and I told him how they were different earlierand they change that's why I didn't know. And he told me that he knew that and noticed how my eyes were green sometimes. I didn't ever tell him the main other color my eyes were, but he knew it. I've been pretty into this guy for a while. I might be reading into it too much but I don't know no one ever remembers shit about me. Is he just nice or did he remember because he's into me?
