When I am looking around in MMA Tycoon, some skills like energy don´t have the same color. It´s changing on which webpage you are on, therefore it maybe a good idea to keep same color on each skill.
Energy (Color : Green) - Is allways green in every game I have been playing - Green means health, youth and vitality.
Morale (Color : Blue) - Blue means peace, stability and harmony.
