Most likely no, in any case not in software. Displays like this are usually single color, some are dual color, at most. The colors are physical properties of the LEDs and can't be changed. If you want arbitrary colors you need a red-green-blue triplet of LEDs for each segment, and I've never seen any of those. Like I said some displays are dual color, for instance red-green, and they will have two common connections (like common cathode), one for red and one for green. It's highly unlikely that the display you show will be dual color. |
