Okay. I'll order the moonlight driver for the blues. And, I'll order two neutral white boards.
The reds are now "playing" nw in this photo.
I'm thinking I might add a red/green board between the two nw boards. But, then I'd rotate the centre boards so they were running the same way as the blues. In the event I didn't like the red/green, I could just remove the wiring for it. It could go on either of the two dimmable drivers.
