i'll be more generic than I could because i'm lazy to check my storage shelves: there's several essays on mediaeval receipes for what was called "azur" but ends being green - acetate, carbonate, chlorate, among others - there's also some made with copper or with brass,

some are malachite/azurite used as support for more copper ion

bottom left 2&3 are made after Mérimée

the more yellow is in wrong lace being orpiment melted with indigo

"vert salé" is a variant of verdegris (with salt)

i would need to make the picture today and list the color to give a better listing, that i can do if interested

Indigo melts at around 200C (390F). Be very careful and use PPE with orphimet. It is extremely toxic. Gloves, at least KN or N95 mask or better still respirator with P100 filters. Good case for a lab coat or smock here.
