Hi everyone

I'm new here so...sorry if I post this thing at the wrong spot ^^"

Now to my problem...I wanted to coloring a picture, but everytime I try it, there is the same problem...On the top of the picture, the color is normal, but on the bottom, it is faint/pale...I don't know if it's normal or not...I try everything, but I can't fix it...I hope someone can help me...
