Neo & Rose
Neo would agree that the pink was much better than the blue, but at least it wasn't real. The blue part was just in illusion and everyone, including Rose, would see blue. But Neo, she could still see the actual pink hair.
She usually got rid of the illusion after a moment, but she decided to leave the blue hair in for now. Yeah, sometimes. She decided not to mention she could alter her entire appearance. She liked that she could change her appearance without anyone else knowing.
