I am a starting out 17 year old model. I would describe my complexion as a caramel shade maybe? I currently have burgundy reddish hair. Should I go back to a natural color like brown or black? Just curious to hear your thoughts.

It probably depends on what type of modeling you want to do

no point in damaging your hair by dying it until you actually need to for a shoot, you'll stand out more with burgundy rather than black or brown and you're better off not working with anyone dumb enough to decide not to work with you because of something as easily changed as hair colour.
