Alright then. Although it was against my better judgment, I did go out and get a Prussian Blue and a Cerulean. The Cerulean I got, though…may need to be mixed with the Phthalo Green or Viridian in order to achieve qualities that would allow it to effectively tone down very warm colors…I haven’t trialed it yet, and so am not sure.
I neglected to see that Daniel Smith (the brand I ended up getting, as that was what was available) had more than one variant of PB36 (Pigment Blue 36). Or, maybe more to the point: I neglected to see that both PB36 and PB35 were pigments for things named “Cerulean.” I was expecting something a bit greener, though got scared when I attempted to check the color in the store and felt pressure releasing towards the cap. Because the people at Blick spent a full 5 minutes (at least) trying to locate what I wanted (and did the research for me), I then was OK with leaving with this.
What I can say is that my “Cerulean Blue, Chromium,” from Daniel Smith is almost brighter than my Phthalo Blue (Green Shade)! That’s certainly saying something!
I’ve tried to adjust the colors here to be accurate to what I saw, earlier. The Prussian Blue is a bit more intense and bluer than Cotman Prussian Blue, but it’s very subtle. They appear to be the same value when dry, it’s just that one (the Winsor & Newton Cotman [student-grade] formulation) is grayer than the other, as an illustration of the quality differential between student-grade and professional-grade. It’s kind of a weird thing to try and describe. Maybe I should take a picture of it…
I believe that the “Cerulean Blue, Chromium,” is PB36…PB35 would have given me something more along the lines of what I expected: a greener blue-green. Because of the way this blue looks, though…I might be able to temper it with one of those ugly mostly-green colors with a hint of blue in order to have the color I was originally going for… 😉
I did get the Cerulean to mix greens and dull down colors, though. It wasn’t something which I was planning to utilize on its own…this is why there is that one gap in my “earth tone” section, in the first image. When and if I get a gross-looking green-blue to mix with the Cerulean, I’ll put it there. 😉
I think I’m about ready to fill my palette, now…
