Arcobaleno Zonenplan -

The name Arcobaleno also refers to how white light splits into colours when passing through a prism. In this zoning model, the "white light" is (living, working, playing, moving). The "prism" is the zoning regulation. Traditional zoning blocks most colours; the Rainbow Plan intentionally refracts them.
