Just noticed a couple of oddities as I go more carefully over the Shin Han PWC dot-card (which my MOST AWESOMELY EXCELLENT
local brick-and-mortar gave me for free, David Art on Arnoult in Metairie near New Orleans, no I don't work for them).
1. What gives with alizarin crimson?
They replaced it, but they didn't. Or did they? We know that the true alizarin crimson pigment PR83 is lovely but fugitive:
Shin Han uses fugitive PR83 in several PWC paints -- Crimson Lake, Carmine, and Rose Madder are all single-pigment tubes of it; Brown Madder mixes PR83 with PY83. Plus, the PWC line offers a tube labeled Alizarin Crimson, which does NOT contain PR83. "Nice," you may think, "Shin Han provides a hue of alizarin crimson, because the real stuff is known to be fugitive." At first this all seems quite sensible of Shin Han. But, then you learn, they replace PR83 with PR23, which is merely another fugitive pigment. Whereas most manufacturers replace fugitive true alizarin crimson with something more lightfast when making an alizarin crimson hue, Shin Han replaces it with something equally fugitive and, to boot, fails to label it as a "hue." Umm, then, why replace it at all? It says Alizarin Crimson, it's not alizarin crimson, and it's not lightfast either. They rate all paints mentioned here as either "High" or "Normal" in lightfastness, questionable given that the pigments themselves are not. This whole alizarin situation makes me ask of Shin Han PWC, yet again, "what's the catch?" I remain skeptical.
2. What gives with Viridian?
They use it, but they don't. Or do they? We know that Viridian PG18 rests very close on the color wheel to Phthalo Green Blue Shade PG7.
See this color wheel https://www.handprint.com/HP/WCL/IMG/intstud19bL.gif
to compare just how close PG18 and PG7 fall on the wheel. Shin Han makes a not-uncommon choice, offering (and, this time, truthfully labeling as Hue) a version of viridian not made of viridian pigment, but of its neighbor. "Nice," you may at first think, "they've made sure I know that Viridian Hue doesn't offer PG18 by tipping me off with the word 'hue'." True, but not helpful, because another paint labeled simply Viridian, without the 'hue' word, similarly contains zero PG18, only PG7. The Viridian Hue and the Viridian are both single-pigment tubes of PG7. So, why offer a label claiming to be the real stuff when it's not, especially when you already have a replacement that claims it's a replacement? There are a few other PG7 paints -- a few mixtures, and two Permanent Greens -- but there is no PG18 offered. Can it be merely for pricing? The stuff labeled as though it is real Viridian sells at middle-range of their five grades; the stuff marked clearly as Hue sells at cheapest.
"What gives?" Haven't figured it out. Maybe, it's a gap in communication or expectation somewhere. I'm almost tempted to suggest that they lack adequate translation services; or, that their printed brochures and labels are wildly inaccurate to the real contents of their paints due merely to mistakes in a printing house that's unfamiliar with Western European letter-forms.
I dunno. I look forward to further discussion. Meanwhile I'm trying them out from the dot-card. The four purely PG7 paints are mildly different from one another, though the Viridian and Viridian Hue seem to me identical. Honestly, they should be.
Quotes from the dot-card and brochure:
"CRIMSON LAKE PR83 ...
ALIZARIN CRIMSON PR23 ...
CARMINE PR83 ...
VIRIDIAN PG7 ...
VIRIDIAN HUE PG7"
But nota bene
PG7 = phthalo green blue shade
PG18 = viridian
PR23 = naphthol carmine (fugitive)
PR83 = alizarin crimson (fugitive)
