It appears to be a software issue, either in the camera's firmware or in
photoshop. Anytime I take a digital photo, I use 'Image / Adjust / Autolevels'
to get the colors back to something approximating the natural color of the
picture. The picture, as it comes from the camera, usually has a color skew
cause by the ambient light being used: incandescent, flourescent, hallogen,
etc. So I use Autolevel to try to recover the natural color. Unfortunately,
when the only colors in the picture are the background white and a largish lego
part in red, Autolevels gives me a result with a distinct blue tone on all the
white areas. Placing the same lego part on a white background with an
accompanying spread of reference colors (1x2 bricks in this example), appears
to supply the software (probably photoshop) with something it needs to sort out
the intended color balance. Mostly, this is conjecture on my part, but I can
attest to the fact that it does make a difference (in my situation) and gets me
the result I wanted.
