How can you "not like" colored names ?
it's a basic feature
Every good game have it for a reason :
-it's a beautiful visual feature
-you can use each colors to reflect on the personality of the characters ( could even change player colors for feminization route )
-and it allow player to know who is talking without reading the name, just seing the colors
When I'm really immersed in a game I almost never read the name, I just see in my peripheral vision the colors or the size of a name, and I know if it's my character or the other one who is talking, it doesn't seem that much but you read way faster like that
At least I did it for me, and people are free to use it if they find it better
