I don’t own any but I’ve read about it, even have two recipes for it. That it remains available as a stand alone hue indicates it is used enough to be, at least, a semi-popular. However, except for one YouTube video showing it being used in pour-painting, I can’t find examples of how it is used.
If any WC members use it (oil, acrylic, watercolor, pastels, etc.), will you be kind enough to share some images of paintings you’ve made using it? Maybe even explain how it effected the painting?
Skill is nothing more than talent practiced relentlessly.
