He's a blue boy, he doesn't want to be blue but he is. He can only feel blue and blacks, he doesn't know what 'pink' or 'yellow' feels like or what 'pastel' means; he'll only know and only be blue. Tyler is a blue boy.
Josh is a colour talker, it's just how he is: artistic. He has a fuzzy pink personality that he's kept with him since he was a little pink boy. He's never blue, he's never felt blue...he doesn't want anyone to feel blue.
I know you're seeing black and white
So I'll paint you a clear blue sky
Without you I am colourblind
It's raining every time I open my eyes
