An easier win for the saturation issue might come when we are able to integrate the raspberry High-Q camera into the OpenFlexure software. I understand that it has not got the offset lenslet array, so it should not suffer from this strong colour saturation issue. That option is still some way off as it needs the next version of the main microscope server in order to talk to the HQ camera, and we would also want to crop the live image.
I am cross-linking this thread to @Yashka’s elegant idea of using a phone screen to provide a colour calibration standard. https://openflexure.discourse.group/t/first-build-basic-low-cost-microscope-v7-0-0-beta1/1365/10. I wonder whether that would also work well for your images here?
