Thankyou for your feedback everyone

I am not a fan of maroon bitones and I think any bitone needs to be special to stand out from the crowd. I wasn't excited about any of these seedlings. I was hoping to create some broken colour irises, not bitones. My favourite was number 19. It was a lovely reddish pink. I will keep number 19 and 4 and maybe 28 for another year. I am planning to discard the other half of the seedlings from this cross that didn't bloom this year. I need the space.
In regard to the different colour blooms on number 3, the second bloom from the same socket as very dark brown bloom is lighter and looks close enough to the other blooms to look like the same flower. The stem is broken now (I may have bumped it when taking photos).
On another stem, there are 2 buds that are different colours. It will be interesting to see if these blooms look similar when they open
