Judging color from snapshots can be a little tricky sometimes but I'm sure in this case the moon was quite reddened by atmospheric effects (normal Rayleigh scattering plus pollution, both natural and artificial). Reddening of the Moon is no different than reddening of the Sun. We may not notice it happening to the Sun until it becomes extreme near the horizon because the same sunlight is also illuminating everything else around us which re-adjusts our internal "white balance" mechanisms.
The Moon isn't actually white or gray in color, it's a bit orange in reality. Here's a plot of the Moon's spectral albedo; it's average reflectivity as a function of wavelength. Our visual sensitivity is strongly peaked in the middle (yellow/green) so the linear slope has less of an impact than we'd expect, but it's still there!
(most of the rest is borrowed from Why doesn't a full/gibbous moon high in the sky ever seem to look orange? Shouldn't it?

As a non-scientific enquiry, I took the photobomb image as-is and used my computer to color analyze the moon. I got this, which does show a definite progression, blue darker than green darker than red:
If I isolate the moon with Python and calculate the average pixel values in the R, G, and B channels, I get [0.33, 0.31, 0,28] which is a pretty good match to the albedo plot if I just look at the plot around 450, 550, and 650nm, (which is what normal people do after spending hours trying and failing to understand the intricacies of human color perception).
