(sorry if someone already use ideas for the game)
1. On character creator, you can have the option to have glowing fur/markings.
2. On character creator, if you want the tail markings to be yellow and the head markings to be orange without making a preset then you can do that when you are coloring the character's fur,underfur and more. Example:
Pelt
Underfur
Eyes
Below eye
Above eyes
Tail tip
Tailmarkings (meaning that the tail markings can be any color without making the other colors be the same color as the tail marking)
Headmarkings
Bodymarkings
Wings.
That's all I got for now....
