The moon appears much darker in that image than it does from our perspective here on Earth. Maybe it has something to do with the fact that from our Earth perspective we see the moon against a mostly black background whereas that view has a brighter Earth in the background? So I have to wonder if that probe looked at the moon when the Earth wasn't in the frame, if the moon would have an appearance more similar to what we see from Earth, meaning a lighter color?

your post has too many errors to mention ---the main one being that you have incorrectly assumed that the readers of this diatribe are as fooled as you are by fake jouneys to the moon...I am the General Hercules of the union of free humans..I am all knowing...I am the enemy of Juda.....

Actually, it's quite dark. It only looks bright in the night sky because of the contrast between space (as seen by our dark-adapted eyes) and the sunlit lunar surface. If you look at the Moon in the daytime and compare it to sunlit concrete on Earth, you will readily see that the regolith is darker. In fact, the albedo (reflectivity) of the regolith varies between 7% in the dark, basalt maria and 12% in the breccia-laden highlands. You are correct, though, that its reflectivity is fairly constant across the visible spectrum.
Pardon the thread necromancy, but I just found this cool video that demonstrates the difference in albedo between the Earth and Moon. At 00:16 seconds you can see the sunlit side of the Moon superimposed on the Sahara Desert. The lunar regolith is much darker:

Keep in mind that video was taken in the near-infrared. It is not exactly true color but cool nonetheless.
The two videos show Earth observed at different light wavelengths, which is why differences in details are visible. The first version uses a red-green-blue filter; the second, an infrared-green-blue.

[Irwin - "I think the Sun might have been striking the rock box that was out and sitting there, ready to be filled with rocks."]
[Jim's photo AS15-87-11796, which he took at 147:19:33 after they got back from the traverse, shows the rock box on the MESA and in full sunlight.]
[Jones - "Things would heat up pretty quickly?"]
[Irwin - "I wouldn't say that. But I know they cooled off very slowly. As I recall, we took them in and we didn't want to touch them with our bare hands. They were that hot."]
[As mentioned previously, the Sun is currently about 30 degrees above the horizon and the surface temperature is about 50 C or 120 F. At the end of the third EVA at 167 hours, the Sun will have risen another 10 degrees and the surface temperature will be to about 70 C or 160 F.]
