His hair became the same shade of auburn as his sister's, and if he did not screw it up, his eyes should have been his original green colour. Though for some reason, his eyes heavily resisted the change in colour and required far more concentration and magic to keep them that way. His face and body remained the same. Any other Transfiguration aside from the animagus transformation was nearly impossible without a wand. He did not dare to even think of experimenting or practising on his own body with it. On the other hand, changing the colour of his eyes or hair simply required a charm, which was far more manageable with his current capabilities. It just was not something he had reason to do before.
