ChAnge your avatar's hair to different colors
Go to 'customize avatar' from your profile. Select 'change features', then highlight but don't click 'hairstyles'. Wait one minute until the 'hairstyles' button spins around. Once it does, select it by pressing A. Choose whichever hairstyle you want. These colors are colors you can't get normally, like blue, purple, green, etc.
