Just to clarify, one side of the LED works as expected, but the other side is not? The two sides should definitely match when it comes to colors. That certainly sounds like a hardware issue with the LEDs and I would reach out to the supplier where you bought it to see about a repair/replacement.
While I understand your frustration and discouragement, this is not “normal” for A&H. Hopefully you can get it fixed/replaced without too much trouble!
