Here is the second report from my lightfastness tests conducted during the summer of 2015 in Ukraine. This time we will look at White Nights, artist’s grade watercolor from Saint-Petersburg manufacturer Nevskaya Palitra.
The tests were run in precisely the same manner as described here in this post. Nevskaya Palitra makes 57 colors, of which I own 46 and a half. 🙂 A “half” is one color which was recently reformulated: in ye olde times, Ivory Black used to be made with a genuine ivory black pigment PBk9, and that is the one that I own and tested here. Now their Ivory Black is a cheaper hue composed of a red earth pigment PR102 mixed with lamp black PBk7 (lamp black is basically burnt wood, while ivory black is burnt bones, so they differ in price, color and texture). I never tried the new version, but theoretically I don’t see why it should present any problems as far as lightfastness goes.
The rest of Nevskaya Palitra’s repertoire are either mixtures of the pigments tested here, or are so glaringly fugitive that require no tests or, indeed, purchasing (such as PY1 or PB1).
As a general comment before I start: in 9 cases out of 47, the manufacturer’s ratings turned to be inaccurate. These paints are very worth using, but if you do use them, make sure you run your own tests. (It’s a good practice with any brand, in fact.)
OK, so let’s look how really lightfast is this cheap watercolor! Continue reading “Lightfastness Tests: Nevskaya Palitra White Nights”
