I've just posted their colour table to the wiki:

http://deskthority.net/wiki/QWERkeys_keycap_colours

If anyone has more accurate colours, feel free to to update the page.

The photo on that page gives the "white" keycap a green tinge instead of a blue tinge. It's not a colour calibrated.

Ideally the bloke here with a colourimetry system would get his hands on a set of sample keycaps ;-)

if you want it i can give it to you

you have there, for reference, a white GretagMacbeth card and a 18% grey Sekonic card

I never did like Shakespeare.

I don't knowingly have any software that will correct a whole image on the basis that a selected sample of pixels is supposed to be a particular source colour.

I make 18% grey D1. At least two of them give me at least one D1 pixel after IrfanView automatic image correction. The one with white in comes out too bright, though. I'll see if I can get the images roughly corrected at some point.

By the way, I'm one keycap short. It looks like nubbinator got one more colour than shown on the website ... charcoal.

a levels layer in Photoshop, if you want i can do this for you so you can have a pure White 250-255 x3 and a middle grey 115-120 x3 and that's good for a photo.
More than this imho you have to use a spectrophotometer or a spectrocolorimeter
Good luck with your research!

That's how these were done:

The samples were photospectrometered with an X-Rite ColorMunki photospectrometer. There's a forum topic about it somewhere ... ijprest did the photospectrometeryering if I remember correctly.

Wait, the background sheet is meant to be 18% grey? So that's 18% from black, not 18% from white (which is roughly what the foreground actually is). I get around #40 to #60 for the background instead of the #2E expected, so that's a long way off — but darkening that would bring the white keycap down a long way, so you appear to have a typical non-linear dynamic range response. That's really going to be a nightmare to correct.

Maybe I'll fiddle with it one day. Not much sense in replacing one set of guesswork with another set of guesswork.

This is a grey card

The X-Rite ColorMunki is used to calibrate display or printer

to measure the color the tools needed are something like that
