This represents the last of the NMM miniatures. It is a Reaper mini called Niroli, Female half orc.
The concept behind this was to show the non shiny NMM, with less reflections and even a tiny bit of weathering. The emphasis here was on a more purplish hue, complimented by greens.
As opposed to the more high contrast SE-NMM, where you are using the bright sky colors vs much warmer grayed down colors, these were from a more compressed range.
Not as high a value contrast, much less saturation, and so on. Everything a bit more muted.
The set of colors is one of my favorites for non shiny metals :-)
