In 1990, Selarón began renovating dilapidated steps that ran along the front of his house. At first, neighbours mocked him for his choice of colours as he covered the steps in fragments of blue, green and yellow tiles – the colours of the Brazilian flag. It started out as a side-project to his main passion, painting, but soon became an obsession. He found he was constantly out of money, so Selarón sold paintings to fund his work. It was long and exhausting work but he continued on and eventually covered the entire set of steps in tiles, ceramics and mirrors.
