If you are thinking about getting a tattoo. You've probably told yourself well, if I get tired of it, I can always get it removed. Here's something you should know before you pick out your design. Some colors come off better than others.
This is from a clinical study in the Journal Skin and Aging, turns out black is the easiest to remove. Also, green and blue absorb light well and respond favorably to laser removal. Red, orange and purple will be more difficult to remove, and if yellow is in your design hope you really like it, because yellow tends to reflect the light meaning you could wear that part of your art, forever.
