Shevia, high five on naming colors after things in the natural world. Besides herbs and spices, I’d go for fruits, plants in general, and elements. Otoh, I want color names to refer to the actual color of the things they’re taken from. It drives me nuts when “cobalt” is used for a shade that’s nothing like the element. Turquoise, the stone, comes in a range of colors, so I’m ok with people using that word for something different than the color I think of first, but cobalt, afaik, comes in one and only one very specific color.
