Let's assume a typical RGB LED, like the one on the SAMA5D27-SOM1-EK board, you would roughly get those colors: - R: red - G: green - B: blue - R + G: yellow - R + B: magenta - G + B: cyan - R + G + B: white I count more than twice the colors as with the simple leds-gpio approach only. ;-) SCNR Alex
