I actually no longer have the white sample case, but I can shoot the two gray and black cases on a white background if that would be helpful.
Are you still planning to make those shots or did I overlook them in the Dropbox folder?
Just got back from Seattle and am catching up on backlog, as I will do tomorrow.
Here is a photo of the gray keyboard on a black background. I didn't have a black anodized case handy, so I just set my black Montblanc pen next to it.
Note that this is with pretty high exposure and a bright studio light, so it's going to look less light and less warm/brown in standard indoor lighting conditions. But I think this image gives a decent sense of the color, on my monitor at least.
Here is with the exposure not turned up quite so much, as it might look in a more normally lit room
