White Enter accent... so an anti-accent? Doesn't work imo, there should be blue Enter and Esc options instead. They appear in the keyboard render, but don't seem to be present in the kit pic.
Big fan of the color palette, but not so sure about this particular implementation.
Edit: These blue keys are going to need to be yellow in order to work, since they're supposed to be mixed with the nav cluster keys (which are yellow). The blue Fn can stay blue since there's already a yellow one below it.
Edit 2: Not sure if you're planning on running this in EPBT or Infinikey (probably the latter, since EPBT likely isn't going to be able to reverse dye sub this based on their current manufacturing capabilities), but if those F, J, 5 keys are flat and not scooped, you might as well drop them and keep just the barred ones, since very few people in the community use flat/non-homing F, J, 5 keys.
