Tetsuhiro Wakabayashi is an artist and illustrator based in Japan, although he states on his website that he’s “interested in international collaboration”. In my opinion, this shows him to be an open minded and creative person, as he is willing to create work with people who may both have a different style as well as different cultural influence, something that could create work very different to his individual style but could also be effective at drawing attention to the art because of how unique it would be.
From what I’ve seen of his work, Wakabayashi uses a dulled colour palette, fairly unusual in children’s illustrations. Howrver, he uses the dulled coloured in a way which puts contrasting colours together to make various individual aspects of the image stand out, some more than others so your eyes move around the whole page as different components jump out at you in turn. I think this can work better than bold colours at keeping a child’s attention as, in some ways, the method Wakabayashi uses stands out more, also giving a level of interactivity with how you view it.
