Why is Fizz Icon Blue For Champion Info Page

So I don't have a picture, but I have the link AND picture of what the icon looks like http://ddragon.leagueoflegends.com/cdn/6.19.1/img/champion/Fizz.png http://gameinfo.na.leagueoflegends.com/en/game-info/champions/fizz/

Is this just a bug or is it some kind of hint towards Fizz
