My first job in Brazil was actually to develop a way to improve the readability of billboards, and based on speed, angle of approach and actually blocks of text. It was very - actually, it was a very good study, and got me a job in an ad agency. And they also decided that I had to - to give me a very ugly Plexiglas trophy for it.
I was born in Brazil and grew up in the '70s under a climate of political distress, and I was forced to learn to communicate in a very specific way - in a sort of a semiotic black market. You couldn't really say what you wanted to say; you had to invent ways of doing it. You didn't trust information very much.
The first time I worked with colors was by making these mosaics of Pantone swatches. They end up being very large pictures, and I photographed with a very large camera - an 8x10 camera. So you can see the surface of every single swatch - like in this picture of Chuck Close. And you have to walk very far to be able to see it.
