Yeah. Many pigments were hard to access or otherwise very expensive. Tyrian purple, for example, was made by boiling a massive amount of rare snails, which is why deep purples were reserved for only the wealthiest of people. In the 1800s, ground up mummies were a fairly common way to make brown pigment.

Kinda reminds me of painted mesoamerican sculptures

That’s a pretty psychedelic color scheme.
