Color slightly off and needs perforation

I was excited to get my die-cut stickers, but two things: 1) the color was a little off. The orange writing came out like mustard yellow and the Red outline came out a berry pinkish red. 2) There's no perforation on the back so it's really difficult to peal the sticker without ruining the edges. I saw someone else complain about that and thought I was safe because I didn't have tiny edges that would get bent, but it was still tough to peel off.
