Tianhuang Set of Colors?

I posted a picture of a Tianhuang stone carving in loquat color and since have been reading everything I can find about this material. My wife just sent me pictures of 4 more pieces from the same collection, she was given one each of the 5 colors I’ve been reading about. These are all Qing or earlier carvings of stone from the now exhausted pit. While I’ve been able to read about these colors until now I’ve not seen them all or been certain if I was correctly understanding gold color from loquat?

Gold color
Loquat

Beautiful carvings, Desert, and very informative.
Good to see the difference between loquat and gold, I have gotten them mixed up as well.

 

This gold colored example is a sale from 2011, prices have risen considerably. I think the color and quality are similar but it is hard to make a comparison between a professionally lighted photograph and an iPhone snapshot.
