While Nik himself does not show emotions his Hair does. So now let´s get into what the hair colors mean......Oh boy, we´re going to be here for a while...oh and by the way, all colors fade into his second hair color besides anger and emotionless also this does not work for the others 1. Blue=Sad(I think we all know that.) 2.Yellow=Default(I kinda wanna keep it that way.) 3 Red and Black=Anger(Why would you use Insanitys hair colors for that?!) 4. Pink=Love(I think they already got that one.) 5.Purple=Lonely(....Wait why would I be-) 6.Black=Rage(....OH that´s why.) 7.Green=Scraed(What would scare me?....oh fu-) 8.Orange=Worried(I know this a dumb question but...why is Orange worry?) 9.Emotionless=Gray and White(....) 10.Sick or Dying=Pale Yellow(.............I don´t like where this is going.) Well that´s it...for now, at least I´ll be adding more colors anywho bye I got other things to do
