This is a minor update, introducing a config option for player's default name color. If you have an old version of this plugin, you should just add the code bellow to your config to utilize the feature. Next update should be able to auto-update config files.
Code (Text):
# Default name color:
# Proper format:
# &<color code> for Minecraft codes
# #<rgb> for RGB codes
default-color: '&f'
