Who?

My puppet may have been created however, I am still yet to find a name for my character and so I have been using 'Random Name Generators' just for some simple inspirations. However, this actually led to me studying the different names for the shades of blue, because I think I would like for my character to have a 'surname' which in some way related to his character/personality/appearance. Shades which I quite like for names are:
Cobalt Blue

Turquoise

 

Oxford

(Tardis blue - which is quite alike Oxford blue)

Sapphire
