Order submitted to GMK, waiting on their confirmation as they're on holiday right now.

Updates: Banderole artwork has been sent to GMK, and samples have arrived. Photos were shot with my DSLR and colorgraded to a Datacolor Color Card. For the GB renders, I had done my colour matching with a 5000k light and a calibrated monitor, so the first setup was getting as close as I can to that. Compared to the kit renders, the green is more vivid, but is the correct shade. In my opinion, it falls within acceptable parameters when compared to the board renders and more real life lighting conditions. Generally speaking, GMK is extremely close in colour matching to the swatches. I'm deciding whether to have additional testing done, but I'm only concerned about the green. GMK has nailed the brown as far as I can tell, but if I have additional testing, both colours will be sent regardless- I have reached out to Nebulant to do testing as necessary. If there is testing, there will not be any change of the RAL swatches that were originally used, only to adjust to get closer to them. However, I have a suspicion that the difference is around a 1-Delta, which frankly is as close as is reasonably possible to colour match something.
Otherwise, any thoughts or comment is appreciated!

November Update:
So, caps were sent to Nebulant for testing, with the following data:
Alphas:
Accents:
When looking at the data, the number that is most relevant is the DeltaE(2000), as that shows the overall colour match, including lightness. Based on the results, GMK is generally very close. A deviation of <2 DeltaE(2000) is indistinguishable to the human eye, while a deviation of 2-10 is considered perceivable under close observation.
If you're looking for a more detailed explanation, it can be found here: https://zschuessler.github.io/DeltaE/learn/
Based on evaluation and the data I've approved the Alphas, but have asked for an R2 for the accents. However, considering how close GMK is on the Accents, there may be some pushback from them, but I believe that its worth the second round. Looking at them next to a colour swatch though, its slightly darker and less saturated, but still within what I'd consider a pretty good tolerance. When put next to the Alphas, the difference is almost indistinguishable, so differences are minimal at best.
I also confirmed with Vala, and deskmat samples are supposed to be coming to them, so hopefully those can be approved soon. :cool:
