I tested this most recently for gifts, for a water themed soap, and I have to say this is the most gorgeous blue I've ever worked with. It provides a gorgeous soft sky-blue color when used in goat milk based melt-and-pour, and gorgeous deep blues in olive oil based ones! It's become one of my all-time favorites in an instant.
I have used this color repeatedly for night sky projects. It is rich and projects a perfect night for watching meteors go by! I also use it for making my Captain America shields. It is just a great go to color!
