In the video of Vsauce2 it is mentioned that
Prussian blue ... it reinvigorated Japanese wood block painting, which went on to influence manga which led to Japanese animation
The phrasing makes it sound like the invention of this Prussian blue is one of the key factors towards the development of Japanese animation or anime.
But was this invention really a key factor towards the creation of anime? Or did this Prussian blue really have a an effect to the creation of Anime at all?
