I know y'all are joking, but since colors represent very different things in other cultures, it feels a bit tone deaf to me. Red and Azure/Green dragons have specific histories, and the colors may have been chosen for that reason.
No worries, I don't think anyone was objecting to objecting to the color pallete. It's just also worth reminding people that American asthenic sensibilities aren't the be-all, end-all. Highlighting the context is worthwhile.
