Tiling over Kerdi and over drywall

kntryhuman

We put "blue board" or green drywall in the shower and around the tubs.

I'm putting Kerdi in the shower. Can I put the Kerdi directly over the green board or do I have to put cement board first?

Can I tile directly over the drywall around the tubs or do I have to put cement board first?

Thanks for the help.
