There are many asking why the Chang'e-4 images of the (far side of the) Moon's surface have an reddish-orange hue. In this answer I suggest that the camera may not use a traditional human-matched color filter set but instead have extended wavelength range to get more science, and so one should not expect realistic color to begin with.
But my question is about this authoritative-sounding explanation published in the Planeaty Society's newsletter as a guest blogpost: Chang'e 4: Why the Moon's far side looks red in new images
The first picture below is an example of one such “raw” image, and I’ve accompanied it with histograms of the red, green and blue channels to show how brightness is distributed in each. In the raw version, the lunar surface looks red because the detectors used were more sensitive to red than they were to blue or green. So although in truth the surface is almost equally bright in all three colours, the green and blue detectors have been set up so as to be less sensitive to light than the red detectors. This is why the green and blue histograms do not extend to the bright end of the range of their scale.
First, the "in truth" part is not defended, and the reflectivity of the Moon really does have an orange tint, see below.
Second, is the argument that the camera's settings are "off" just that the histograms show different levels? Isn't this just exactly what you would expect from an image dominated with something orange?
Question: Am I missing something, or is this explanation not at all an explanation, but instead just some internet gobbledegook?
