ReSpeaker 4mic array LED Colors

Hello All,

I have the 4Mic Array up and working fine, but I really am having trouble understanding the way the LED lights are called in either the Alexa example or the Goggle example. For example, the Alexa one has a blue ring of led’s and a green one in the position that matches the direction of the awake word.

My question is simple, what if I wanted to simply switch and have the ring green and the pointer blue?

I just can’t seem to figure out where the color is located in the sample code located in Is there anyone out there that understands the code enough to point me in the right direction?
