I love stop-motion films and since coming across this site - We Love Stop Motion - I have an endless supply to watch.
Many of them show great uses of colour and here are some examples:
This advertising film, not in English, all about ceramic tiles. Great use of colour and the language barrier doesn't stop it from being educational.
Organising a book shelf- the colour fun in this is great
Nils Inne Playground by Jeremy Hugues
Mushroom Tea by Max Martin
How much does this one make you want to play with paint?
Fun and colourful firework
There are may more films to watch but these were the most colourful ones I found today to share with you
