Strange, but true.

I made a test pattern composed of red dots and placed some distance away
from
EOS-1D Mark III and adjusted the zoom to match a 35mm disposable camera.
It turns out that my red patter appeared green on the image captured by EOS.
The 35mm film on the other hand captured my pattern in undistorted red
color.

After doing some research on the sensor technology I've found out
that all mosaic type CCD sensors are not able to capture correctly the color
(chrominance) portion of an image
element that is as small as the CCD element.
Which means that since it take 8 CCD element to determine color, source
image need to have uniform color
with areas that are at least 8 pixels large  for correct color acquisition.

That incredible technical deficiency makes all the cameras that use mosaic
patterns
a false image producers and logically they should not be used in
applications
where true images are required. In scientific, medical, law enforcement and
may other application
areas this type of false images would substanicialy degrade performance
quality.

The cameras with mosaic type sensors should only be used for entertainment
purposes.

If You want to capture true images with undistorted color than the cheapest
way is to use
35mm disposable camera.
