Here's an ad campaign that has been good for both gray spaces and world paint manufacturers called the Let's Colour Project. It's an international campaign to brighten up drab spaces with color... or colour as they say in jolly old. But is it a project or is it an ad? Sure smells 'ady' to me. Still it's an impressive two minute long example of some well thought out time lapse filming of some immense spaces as they gain color. It's fun to watch and a fun listen to - some great music. The campaign created by EURO RSCG London is for Dulux. Hopefully you won't be surprised when you are told Dulux is a world paint manufacturer. Lots of docs were shot in various cities around the world where the painting occured - here's the YouTube Let's Colour Page.
