Sanna Annukka did this for the band Keane (below)...its the idea of no outline that I liked about it.
Same here with Dylan Forman. I think colour it vital in everything we do...it gives the piece a much more professional look. I think sometimes we over look colour, so thats something we need to think about.
I liked the flatness of these screen grabs taken from an animation called 'Thursday' by Matthias Hoegg...also the colour again
Here's a test I did. To be honest, i dont know how it fits in with the stop motion pop up book idea yet...maybe its just the idea of using block colour for the building and camera etc...
