Is coloring the back of my cracked iPhone bad?

So I have no clue how but there's a tiny crack in the back of my iPhone in my bottom left corner, its not the whole back, but I've really wanted my back to crack so I could color it, but is it bad for my iPhone?

Uhh… Not a very good idea. You could end up drawing on the boards or wires inside your iphone. You can color the not cracked areas but be very careful coloring the cracked area or you could end up damaging your iphone. Also how are you coloring your iphone?

(i'm not a pro at apple products but I learned this firsthand the hard way. )

also if you know about pianos could you answer my question? "Which kind and brand of pianos best for digital recording and songwriting?"
