Specific Can you change shirts color?

[Restav]

Dear PhotoShop Gurus,

The dog company we used to work for is no longer in existence. Is there any way to change people's shirts to avoid the purple and the yellow logo? Same goes for the dogs with the purple bandana and logo.
Plain regular one color shirt would be great!.

Thank you,

This was fairly difficult, but here's my try. I also took some of the glare out of the sky.

Went with green as well as a few lighting changes.
