Prussian Blue
As a general note on Prussian Blue, we advise doing one's own lightfastness tests in different white paints to see how this pigment may behave. Some preliminary research may indicate that the lightfastness of PB27 may be affected by the use of various mixing whites. One resource on this topic is a video from Rublev/Natural Pigments which shows their tests from their own variety of Prussian Blue (PB27) in various mixing whites. In this case the combination with white created different lightfastness ratings: https://www.youtube.com/live/xFn74zdaDHc?feature=share&t=1286.
This color is sometimes called Prussian Blue, sometimes called Paris Blue. Note from brand in German: Traditioneller Farbton. Sehr farbstarkes Schwarzblau zeigt seinen eigentlichen Farbton erst in der Lasur neigt wegen seiner hohen Pigmentierung zum Bronzieren. * ehemals: Preußisch- Pariserblau formerly: Prussian- Paris blue**
