My work is based on the combination of colors coming from different systems. Recently, I have concentrated on the gamme used in coding metros around the world.
For example, struck by the color I glimpsed each time the door opened on the Independent Subway line in New York City, I decided to transcribe its color coding. The subway line differentiates between local and express stops by a systematic change of color. My color chart painting of how it works has 44 different colors and 114 swatches.
