It is right that a spell will not change your physical appearance or genes and DNA, such as: eye color, hair color, etc. This is very true. Energy manipulation and desires will not change your physical appearance or your genes and DNA. I agree with that Pagan, such things will not work for anyone who try that since spells are basically energy manipulation and direction...
However, there is a form of glamour spells which is known as something that works. So saying that it is not fully possible is not fully correct. The form is called: "Illusions".
Basically glamour spells are illusion, nobody says that they actually changes any part of your body or your actual physical appearance or DNA and genes. Such spells are known as putting and illusion on your self and other people around you.
A glamour spell will only change your opinion and your point of view about you beauty and appearance, same thing about other people who are around you. However, nobody said that this changes something actual about your physical body or appearance.
So this is why this is called an "illusion".
This is actually not a bad thing to do, yet it won't change anything about your genes and DNA but it will change your own mind and thoughts. This is actually even a helpful thing, because sometimes it is very important to love yourself and to think about yourself as beautiful - from the inside and from the outside.
But you do not really need a spell. Just love yourself and believe in yourself and you beauty. If you do it, other people will start looking at you differently.
But as I said, such spells are possible but they do not serve what they sound like, so please keep that in mind.
These glamour spells are false. But there is a thing to change the appearance of eye color change. By wearing yellow shirt, eyes will appear more green. Wear purple, and blue eyes become a dark bluish purple. But doing a spell to change your appearance is a waste of energy. Take time to care for yourself. When you look good, people around you see it. Proper diet will also improve one's looks. Even believing in yourself will show as confidence. Be Well...Blessed Be...
Maybe i did't make this clear, i know the spells don't work but i was more boarding on the lines of psychic, more than magic. And when i say glamour i mean changing how people see you not changing yourself.
