This picture actually stems from a conversation I had with Kite almost a year ago. We were talking about why Ran acts like he does and about her character that is with him. (Yes he is one of my alternates but simply because I loved his design and his personality was very close to mine.) Yeah he wears black boxers for a reason. XP

Ran changes color and intensity of glow dependent upon mood. Meaning if he's sad or depressed he won't glow at all. He can glow more than one color at a time. (For rainbow each glowing band on his tail is a different color. he has 7 of them)
