As a general note, there is a lot of overlap in the names between Charvin’s Super Fine series and their Extra-Fine series. The Super Fine Series is sometimes just referred to as the Fine series, and the tubes only come in 150ml quantities. In contrast, the Extra-Fine Series has a range of sizes. On another topic, there is a bit of uncertainty in general about which pigments are used in any given paint. We reached out to Charvin about some questions that came up and there was not any greater clarity. Some pastel convenience blends of theirs only list a high chroma colorant and do not disclose the white used. This could be an issue if zinc is used. Also there was a green with only a yellow pigment listed, so be aware that not every pigment may be included in their brand statements.
