Quercitron Lake (Brown Pink) From inner bark of Quercus Tinctoria. 

Editor: This is "Quercitron Lake (Brown Pink)" by Winsor & Newton. It's so interesting seeing the raw pigment next to the paint sample. What strikes you when you look at this piece? Curator: The color of this pigment sample evokes a sense of earthiness and natural warmth, doesn't it? I imagine the artist's fascination with coaxing these hues from the inner bark of the Quercus tinctoria, unlocking the secrets held within nature. What do you think about the contrast between the pigment and the painted sample? Editor: It’s fascinating! One is raw and the other shows its potential. Curator: Exactly! There's a world of artistic alchemy squeezed into this tiny vessel. It kind of makes me want to go forage in the forest, doesn’t it?
