Photographers using technical camera may sometimes see a colour cast. Don’t panic.
When using technical view cameras with digital backs one needs to understand that the image may have a colour cast. It occurs prominently and is more pronounced  when movements are applied to the camera.
As the lens plane and the CCD plane are not parallel, the incoming light rays hit the sensor at varying angles, thus creating a colour cast in the image. This has to be corrected by using a LCC filter. Just shoot a frame using the LCC filter under the same lighting and camera movement and aperture setting , then after you have shot this image, go to the raw processing stage and use the analyse tool. After you have analysed the file, copy the analysed image settings  and apply this analysed factor on the actual image in the RAW processing stage.
The final image will be rid of the colour cast.
