Hello, I’m using a 64x64 adafruit rgb matrix and a rpi 3.  
I’m wondering if it is possible to vary brightness for individual pixels or groups of LEDs? Eg. Loading one image in at 50% and another at default.

yes, you can adjust the brightness of the whole panel, but not anything less than all of it
