What will be the concept of Taemin's upcoming solo album?

My suggestion would be Taemin in red-hair with more darker and more sexiest concept as well as a torrent of himself rapping!

Personally I think Taemin is sexy what ever his hair colour is ! It’s those eyes that are simply both hypnotic and mesmerising, that look in his eyes ! Fantastic ! Wow! Sorry I’m back ! I think I like him with the blonde hair ! ,but I can see your point !
