Normally, one would say it would not work, and another response would be that it would just be an illusion, that they wouldn't really change, however, you can go ahead and try it to see if it works for you.

You cannot change your physical body through the use of spells or other magic. Magic will not alter your DNA. Of course you can go ahead and try it, but it would be a waste of time and effort in the long run. As NiamhWitch says, you'd have better luck with colored contacts.
I remember reading up on things like this a while back and no matter how hard I looked I always came back to the same answer and that was you can not change your body at all with the use of spells. As stated above an illusion may be possible.
I would think though even if there were spells that could and would work it would probably be very dangerous.
Sadly, it is not possible. However, you can use an illusion, i.e. Glamour Magick to make some think it is a different colour. But magick can not change anything physically on yourself or others, nor can it change your DNA. Though, feel free on trying to do so.
