These constants were actually backwards from the way they were named.
Active3was intended to be RGB, andActive3BGRintended to be BGR.I confirmed the pin orders on the schematic for the triple matrix bonnet here: https://learn.adafruit.com/adafruit-triple-led-matrix-bonnet-for-raspberry-pi-with-hub75/downloads
And by running the single panel simpletest on one of the same panels that I ran the triple matrix test on. With the change from this PR both now draw the colors expected on the same panels using the same RGB pinout configurations.
I changed the triple matrix simpletest example to use the default pinout instead of the BGR one. This got set to BGR before due to the pins being internally swapped.
