Hey hey everyone, got an email from GMK just yesterday and felt it appropriate to share.
Colour samples should be no later than next Wednesday, and Christoph seems confident in the purple, and I can practically guarantee I'll be going with the original alpha colour.
I will also be getting some help from my sister's friend who has a very nice camera and lots of experience, so she can take some very colour accurate photos of the keys, to give the best idea of what to expect
If you have any questions, ask away. I'll do my best to answer them.
