If the colour accuracy is so damned important, I'm willing to take images with correct colour balance. IANAProfessionalPhotographer, but it's weird how much stuff you pick up when you have a really good camera store in town... I have a camera with flash (Fuji X20), a Colour Checker passport, a white balance sheet and a pop-tent for taking pictures of small stuff.
But you know what? It would look almost exactly like the image above me, and you STILL wouldn't be able to tell if the image you actually see is correct, because your screen isn't balanced against the picture I would take!
So just chill the **** out and wait for the caps! If you like them, fan-damn-tastic! If you don't, SELL THEM!
