Powder blue with a trace of yellow

The clouds are purple
  Like the dress I wore that day
  Ink of the pen you used to sign the receipt
  The flecks of paint you tried to remove from my fingers
  That one wall of your room that's not covered in posters

The sky is powder blue with a trace of yellow
  Like the shirt you insisted on wearing that day
  The shirt that, I later found out, was a gift from her
  The shirt she got you, because that was her favorite color
  The shirt that assured me that I was being replaced
