I did this spell that sort of worked for me. My eyes used to be light brown and they changed to amber (which was not my desired eye color). I kept doing this spell every day and now they changed from amber to brown with a tint of purplish gray in it (it's hard to explain). My friend did this and her eyes used to be chocolate brown and now their hazel. We realized that we never got the exact color we wanted. This is because you need to concentrate on the spell only and only on the spell. If you think about something else for one second, the spell is doomed and your eyes will change to a different color.
This is the spell:
Supplies: A orange and pink candle
When: At night
What to do: Close your eyes and think about the color your eyes are now for exacly 5 minutes. Then think about the eye color you desire for exacly 5 minutes. Then chant, "Become of me, become of me, become of me." Repeat this process once more and then watch your eyes change color throughout the day.
