Another excellent video. Thanks for sharing all the information. I think the person from Prodigal Sons got hold of an old stock of manganese blue. Also manganese blue genuine made me smile. The version from DS is weird as it is fluorescent under UV light. So there is something they are not disclosing about their version.
I am not a snob about lightfastness, but I do want to know the pigment information of the paints am using. I buy mostly single pigments but am very interested in convenience colors and what they are made of. This is the most thorough channel I have seen as far as pigment qualities. The websites you suggest are complete sources of information. You are appreciated and I am subscribed.
