The shadow square, also known as an altitude scale, was an instrument used to determine the linear height of an object, in conjunction with the alidade, for angular observations. An early example was described in an Arabic treatise likely dating to 9th or 10th-century Baghdad. Shadow squares are often found on the backs of astrolabes. (Wikipedia).

Colored Shadows Exhibit I Exploratorium
Not all shadows are black. Red, green, and blue lights shine on this wall, combining to make white. As you move in front of the wall, your body can block one, two, or all three of the lights, resulting in shadows of various colors.
