diagram for demo

Cyan, magenta, and yellow filters mix subtractively on OHP. Cyan, yellow and magenta filters can be placed by themselves or overlapping each other on an overhead projector. The resultant subtractive color is displayed on the screen. Cyan + yellow gives green. Cyan + magenta gives blue. Magenta + yellow gives red. Magenta + cyan + yellow results in black.
