This is an automatic color of interest to me because I love teals and turquoises!
Prussian Blue (PB 27) is a cool (green-toned) blue with a classy subtlety. On a scale of Moody Emo Teen (Indanthrone Blue) to Manic Pixie Dream Girl (Phthalo Blue Green Shade), I would put Prussian Blue somewhere in the middle.
Phthalo Blue (Green Shade) uses PB15:3, a green-toned variant of phthalocyanine blue PB15. (There is also a more middle blue variant, Phthalo Blue (Red Shade), which uses pigment PB15:1 or PB15:6. See my post, What’s the difference between Phthalo Blue (Green Shade) and Phthalo Blue (Red Shade)?)
Every major manufacturer offers some variant of this pigment, and mostly they share some characteristics, like being bright, bold, and highly staining. Daniel Smith’s version is even more bold than usual/than the rest of its line, so expect LOTS of color from this paint! It’s super-vibrant and actually kind of hard to mix because it has a tendency to overwhelm whatever mix it’s in.
