I worked the past weekend and nights using the Freescale FRDM-K64F board with the colorful Adafruit NeoPixels (see “Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 1: Hardware“). These RGB LEDs can create beautiful colors. For for the non-geeky readers I have a more ‘natural’ one:

The beautiful colors in Yellowstone National Park (USA) are the result of pigmented bacteria that grow around the edges of the mineral rich water. I very much enjoyed it a few years ago, cannot wait to get back there.

Happy Coloring 🙂
