Actually half siders can be any combination of colours and mutations. There is a half sider in the UK that is half cobalt and half grey feather duster. Might be able to find a link for it.
There is also a member here who posted pics of a baby asking if it was a half sider - it most definately was (half blue half green). Try and search for it
