If it's in the case of a specific building, you have a to do it. Light is very different. I was looking at Washington this morning with the snow. Even if it's bright, there's a complete different light than what you would find in California or in Mexico. So that's again a reaction.
Culture has to do with it.
Mexico is a country of color. So to use color in Mexico, I sometimes say that we are almost irresponsible in use of color. To use color on the East Coast is completely another thing. We're doing the students residence for the University of Chicago. It's very interesting because they're asking us for color, and at the same time, we want to respect Chicago and not just arrive there and say, here we are, the Mexicans, with our bold colors.
