I'm having a hard time picking colours.

Bear in mind that these are VERY VERY rough pastels over the top of photocopies and definitely not works of art (I almost didn't share them since they are so bad but I really need lots of opinions so please speak up if you have a favorite).

I've got a few different colour options, one is kind of pink, one more yellow and the last one is more grey. When they are next to each other they look won't but alone they look fine.

Pink (option 1)

Gold/orange (option 2)

image

Grey (option 3)

Which one is best?
