In this video I’m comparing Viridian watercolor paints that are labeled PG18 (Pigment Green 18), because I’m honestly tired of Viridian that feels weak, chalky, or just plain hard to re-wet. Viridian is such a gorgeous emerald green when it behaves—especially if you love granulation and you want those color-separating mixtures that look alive on paper. I swatch and test the paints side-by-side so you can see the differences in strength, texture, and how they move. A big focus here is honey-based watercolor, because it can make a huge difference in rewetting and overall usability. I talk about M. Graham (my go-to for that creamy, easy-to-rewet feel) and also mention Roman Szmal’s Viridian in a pan as another really nice option. I also share an important pigment-labeling note: I suspect Lukas’ newer Viridian batches may include PG7, because the 2020+ tubes I tested behaved like PG7 (very fine particle size) rather than the more obviously granulating PG18 I’d expect. If you’re choosing a Viridian specifically for granulation and separation, that pigment code detail matters.
