I'm not fond of earth tones on my lips. I think they're ugly. I prefer bright reds & corals.
Don't you want to have the natural look?
IMO red, peach, or mango just don't match you; I can see some darker corals but there are probably not a lot of corals that compilment your skin tone, which I find to be exquisite.
Earthtones (IMO) probably compliment and/or enhance your natural tones i.e., (untouched skin color).
IMO, for your skin color, corals takes away from your natural beauty because they distract from your natural skin tone but earthtones say "I am naturally beautiful just the way I am!"
Try it! If I am wrong I stand corrected!
