We see the yellow Sun as a sodium vapor lamp, in balance, but we are balancing the highlights in our minds, routinely, here on Earth. The process of seeing the differences, is interesting while making Mars look more 'neutral' within the ranges of differing receivers they are using in the cameras, both landers and satellites.
HiRISE images when balanced can have a yellow highlight tint which is 'realistic', but noticeable, in some photos.
I suppose the pattern of the scoop clump I showed is perhaps some shapes on the equipment, perhaps.
Do you have a non-command-line program for the color registration process as yet? A GUI program for the lazy of mind, such as myself?
