Okay - here's what excites me about dyeing my own fabric. This black is just like most black horses - from a distance they look inky. Step up close to pat a flank and you discover that their color is more likely a layer of dark brown, rusts, with black dusted over the top.
In this instance, iridescent paint too. Behind that one is one of the two rusted pieces that came out so well.
The teal damask has an overlay of iridescence too.Impossible to photograph but still gorgeous.
