These pants were the closest to "rainbow colors" I could find. I bought these for my daughter's birthday with a rainbow theme. She loved them very much and they fit as expected. The only downside is that they shrink a bit after they come out of the dryer. But I expected that. They are stretchy so they still fit her perfectly.
