Everyone knows about those "bi-color" LEDs, right? You know the ones. Hook up one side, it glows red or orange; hook up the other side and it glows yellow-green; hook both sides together and it glows some variation of yellow.

Well here's one you probably haven't come across before: bi-color (2-chip) LEDs that glow red, blue, magenta, or any variation you can get using red & blue (think purples and deep pinks and such).

It's glowing red on the left, not yellow like this picture shows

The color can be varied of course, if you vary the input to each chip with a digital circuit. But a simple pair of resistors will allow you to select one of three colors from a single pole power source like a battery.

Looks like common cathode. Anyone interested? The price will be right.
