I really like this recolor. I think that the best part of them is that since they are "constructed" out of bone rather than being skeletons it removes the expectation that their bodies should be painted "like bones". Undead armies have always had an issue looking similar since the major aesthetic and color scheme is "bones all the way down" .
Vampire Counts got away from this by including Vampires, spirits, undead wolves and bats.
Tomb Kings got away from this by including a bunch of constructed and going heavy in on the Egyptian decoration (mummies, masks, armor, big shields, things made of "not bone".
This new army gets away from the bone problem indirectly. Their non-bone bones can be painted in other colors to simulate other materials fairly easily. You could do grey stone, red stone, obsidian, marble, jade, terracotta, or even metal. The possibilities are really astounding.
IF I collect them, I've already got my idea: Terracotta "Bones" and Jade armor.
