Indanthrene Blue. What a name. I love the coldness of this color & the fact that it is made using salt. It is one of Winsor & Newton's colours with a Permanence rating of A, which means that it goes from very light to very dark with a smoothness. While I make the paint repel itself & become granular with the salt, I prefer it to start even. I am sure this color will be showing up in my paintings soon. Happy Friday Y'all!
