These are the 2 hair colors I am thinking of. My skin color is pretty much the same as Demi Lovato's with the only difference between us coloring wise is that my eyes are a hazel (& are appearing greener as I get older apparently). Should I take the plunge? I also have pics on my profile of a recent pic and one with me when I have a fake tan. Again for a natural tan refrence, look at Demi's skin tone.
I like how it looks now, but I think you would look nice with the other colors as well. I would stay with the current hair color unless you're really bored with it. There may be ways--with software, websites or wigs--to see how you would look without having to dye your hair. Or you could try some temporary dye to test it out. Good luck!
I think you are a very pretty typical dark-haired girl, you do and some like Demi Lovato,I don't suggest you dye your hair colors, your hair and your skin is very fit, first saw pictures of you feel you are very attractive, but you hair coloring after I don't promise that I would think so.
Personally I think your hairstyle is attractive as all else as it is right now (bangs are super attractive in my opinion). A a dark brown would probably look good on you as well. But honestly, my impulse is not to change a good thing when I see it. You've got a good thing going on there.
