Wait, you're trying to color-match against a specimen by _reading
color values from the screen?_

Does this not strike you as unnecessarily circuitous? Or fragile? Or
prone to unwanted interference from monitor color calibration?

Why not use ImageCapture to actually get the images straight from the
input device? Or if the user already has an image (preferably with an
embedded color profile), let them import the image file directly. Then
you can present your color sampling interface without any silly
screen-reading trickery.
