0.1.11 Projected Colors
A set of color filters can be projected in a triangular overlapping circle pattern. Filters available are red, blue, green, and minus red, minus blue, and minus green.
The Rav'n light is a small pulsing light that looks white. When swung around on a string you can see that it is made up of only red, green, and blue pulses.
Also available is a hand-held color mixer. This device has a tricolor red, blue and green LED with three switches. By pressing two of the three switches, the secondary or negative colors are made and by pressing all three at the same time we get white light.
Participants at a workshop show the seven possible colors after making this little color mixer with a tricolor led. This is similar to controlling a single pixel of a 3 bit RGB display. Black is the eigth color.
The tri color led can be found here.
