Dunno if I am the only one experiencing this but it has been for a while. When changing colors for your body and you end up changing 4+(or maybe it was all colors, I forget) the last color changed doesn't change when you exit the editor. I don't know how to explain it better, so just go try for yourself lol  

I've had that problem too but sometime when I tap on the place I want to change it just wont open up the colors for me :/ I can tap other things though  

same here  

Happens to me as well. I just keep changing the color that didn't change until it does.  

I fix that by restarting the app.  

Happens with me too.
Ways to fix it yourself are to either restart the app, like already mentioned, or just change the colors a few times.
The second solvation I posted doesn't always work, but it helped me out sometimes.
Since it's quite annoying though- please fix this bug.
Thanks.
