Ok then who is still in this and who isn't still in this then I see a lot of confusion over custom colors that are really pointless. If you really want a custom color just go ahead and take it but it needs a canon zord to go with it. 

As far as I'm aware now here are the following colors that need filling

Blue and Black

The colors taken are Green and it's Dragonzord, and Yellow and it's Sabertooth Tigerzord as far as I'm aware at the moment.
