Many of your constructions are in white concrete. What influence do artificial light and natural light have on colour?
I have done many white buildings but also green, blue, red and every colour you can imagine, It depends on what is the best circumstances circumstances. For example in the South of Portugal, the style of those buildings is generally white because that helps to reduce the effects of the sun, so it benefits the interior. If I'm building in the Netherlands for example, where the light is not so strong, I will probably choose other colours.
So, you see, the cities, and even the relationship with what already exists are different. For interiors I often use white paint, although it is never actually white. Pale colours help to like the space very well and allow better use to be made of it, with less energy consumption.
