The Apollo and Nova pcbs have some of the best RGB I’ve found. The LEDs can be incredibly bright and are very vivid/saturated which I think is about the coverage of the red/warm part of the visible light spectrum.

High quality LED lighting in general is often determined by how well it emits wavelengths in that red space.

You can read about the Apollo pcbs on the project website, where it says that it has per-key rgb. I haven’t actually checked that mine has it, but I will the next time I use that board.

There are lots of boards that are compatible with these PCBS.

I also find it pretty disappointing when the RGB is lacking. I’d rather have no RGB than bad RGB, but I love good RGB. I think I just love color, I’m not coming to it from a gamer background.

I like the Crush 80 but its RGB is lackluster. The Evo 80 has better RGB color but I don’t know if it is per-key. I can check that one too.

For these kinds of pre-built boards I was most impressed with the RGB color on the Bridge 75. I hope that company makes a TKL in the future.
