The FW16 keyboard controller is an RP2040 running QMK open source firmware. Last I looked, standard QMK does not yet support OpenRGB. So the FW16 probably won’t support it out-of-the-box.
But if I recall, there is a QMK fork that supports OpenRGB. So it’s possible it could be added some time later, either offically by Framework or via the community. It’s not on FW’s github last I looked.
