Is there a risk that my hair will turn green?

Ash tones are the most complex in this case. It is best to consult your cosmetician if you want to use an ash tone in your hair. 

Chlorine can also alter the color of your hair, especially bleached and blonde hair tones. It is important to rinse your hair immediately after swimming, as well as washing your hair with shampoo specially designed for blonde hair to remove chlorine residue from your hair and neutralize it.
