Another update here. I've been really busy with other stuff lately, but I have talked with zFrontier and Keyreative and they've agreed to produce the set. So that means KAM profile instead of DSA. I'll be sending out color chips soon, so they can start matching and getting samples back to me.
I got a load of plastic chips from Pantone to try and get the colors as close to the original vision as possible and after a lot of trial and error, finally nailed down a set that I think works. All of the images have been updated with the new colors, and I also did a few renders and added them to the original post. (I also added a photo of the chips so you can get and idea of what the colors look like in the real world.)
I think I should have a more solid grasp on dates and prices and everything soon, so hopefully another update shortly.
