Unfortunate update yet again,
I received my "full set prototype" (the entire accent kit and any of the multicolor novs are missing, presumably because these require reverse dyesub).
The alpha and modifier keys do not match the blanks that I approved nearly 4 months ago now.
PLEASE do not make final color judgments based on these photos, they're crappy cell phone pics purely to demonstrate the difference in color between the blanks I recieved previously vs the new "full set" of samples 
This lighting is atrocious but it is what best allowed my camera to capture just how DIFFERENT these two colors are. Above is a BRIGHT pink enter key, below is a pastel pink blank. These should be the same color

left is the approved beige blank, right is a borderline brown blank from the new samples.

Under a bright ring light the difference is less noticeable, however IMO the pink is still far too bright on Enter sample compared to the original sample ( and this light is brighter than the light pantone recommends you match under, I'm just trying to best photograph what my eyes see )
I will also be having them change this pink legend color., its far darker than the renders so I'd like to bring it more in line with them.
The only good news is the Green on green. orange on yellow, and black on grey novelties look great and can be approved.
It has also been revealed that EPBT handles their queue VERY differently than other manus like GMK. Instead of spots in the queue being secured upon invoicing, spots are secured upon sample approval. This means once you approve your samples, you're put at the END of the list of sets with approved samples (Even ones that haven't started production yet!). EPBT/KBDfans cant give any reason why they do this rather than like GMK where if your spot in queue comes and your color aren't ready, they move onto the next set and then come back to you. This means people who bought sets like my own and EPBT Aesthetic that struggled to even get samples from EPBT get double screwed by long wait times.
