(Feedback Welcome!) Minor/Major: Colour vs Black and White

After developing the character designs for the Catcher and the Fairy I realised that although I had decided on making the animation in black and white I haven't explored the possibility of making it in colour. These are not final colour designs but an idea of what they could look like, feedback is welcome on whether black and white or colour would be more appropriate :)

Orange, Brown, Red

Purple and the original Black and White
