it's simple really if
"Mylotian" is being used commercially
that's copyright infringement plain and simple

If not and that's only a nick-name
"No"
cadbury tried to get daryl leas chocolate for using the same color purple
claiming it was copyright nearly sent leas bust with legal costs (mega $$$$)
was dropped in the end as courts ruled a color can't be copyright
I personally wouldn't bother with it
