Charvin Super-Fine Burnt Shadow may not be available in all regions. A note on availability for painters in the U.S.A.— at this writing, for colors not currently stocked by Jerry’s, Charvin informed us that these colors cannot be ordered directly from the Charvin store. For painters in other parts of the world, it might also be a good idea to contact Charvin before ordering directly. More information about this color can be found here: https://charvin-arts.com/gb/super-fine-oils/312-burnt-shadow.html. In general, we did not categorize any Charvin paints as single pigments. The brochure has pigment listings which do not seem to account for the final color, such as pastel blends which only listed a high chroma colorant and did not mention any white pigments. This could be problematic if zinc is an ingredient. We reached out to Charvin about this and were directed back to the brochure. On another note, in general it may be helpful to distinguish between their two paint lines: Extra-Fine and Super Fine. The Super Fine oils come in quantities of 150ml and the Extra-Fine come in a wider range of sizes. There is a lot of overlap in the paint names between the two series.
