July 10th painting notes

I did eight large paintings today, July 10th, using up some extra paint I had on hand. The tubes I finished off were PB27 prussian blue, PB29 french ultramarine, PB15 phthalo blue,  PY175 winsor lemon, PR233 potters pink, PV19 permanent magenta, PR209 quinacridone red, and PR122 quinacridone magenta.

Notes:

PB27 prussian blue, from Holbein, the lightfastness was only 2 stars which is bad for a Holbein paint. It may also have aquatic toxicity.

PB29 french ultramarine, from Winsor Newton, I love this colour but it is acid sensitive. I wont use it from tube in my main palette anymore, but I still have a nice version in the Stoneground pan form for special paintings. If I use ultramarine blue I will note it on the back of the paintings from now on.

PB15 phthalo blue, from Sennelier, this was slightly runny and very old, I bought it from Sennelier Rive Gauche, 2008, it was old when I bought it!

PY175 winsor lemon, from Winsor Newton, I love this colour too, a transparent yellow, but it may have ligthfastness issues, although it seems to depend what source I read. It was also redundant with my new vanadium yellow, and the benzimida yellow.

PR233 potters pink, from Winsor Newton, hey I had fun with this paint! But, it had so much gum arabic and dispersant that it did not mix well with anything. The colour on its own was okay but not so useful for landscapes. This is a pigment meant for ceramics, but adapted to watercolour. Probably good for florals.

PV19 permanent magenta, from Sennelier, a very dark rose-red with granulation. Love this paint, but the Sennelier formular contains a lot of honey, so it turned into a syrupy mess in this extreme summer heat. I will replace this paint with another company maybe ShinHan PWC or Daniel Smith.

PR209 quinacridone red scarlet. Also from Sennelier, a very old tube bought the same time as the PB15 on Rive Guache (Paris). It wasn't runny, its just that I have a newer version from Holbein, called quinacridone red cherry.

PR122 quinacridone magenta. From Schmincke. What a shame to go through a whole tube of paint I just bought, but the lightfastness was only 3 which is good but not great for Schmincke, and they do their own tests. The good news is that one of the paintings I did today with this colour was a big hit with Cilei. I will post it here soon, but I need sunny day with no rain to get a good picture of it! It's called 'Your Melting Heart'.
