How does it mix with granulating colors? Do others have issue with it, besides the fact that its such a powerful mixer?Īs for pigments like Cobalt Teal and Cobalt Turquoise (I found that they worked similarly)- they’re primary use for me is to make a broad range of relatively vibrant, yet natural greens. I’ve been resistant to using Pthalos in general for a long time, but in limited use, it seems for helpful. I’ve just never found a consistent use for Prussian Blue that wasn’t just as well satisfied (or better satisfied) with Ultramarine Blue. This just doesn’t seem as useful as the shift from the more violet blues of Ultramarine and the warmer, orange tones of Burnt Sienna- particularly for landscapes. But I’ve found that the grey shifts between the greener blue and the duller red, in terms of the range of possible mixes. It’s funny- I’ve used Prussian Blue before, particularly when mixed with a red (like Indian Red) for greys. For that, I can his keep a tube in my backpack for the occasional use. Occasionally, I want a daub of middle blue for a shirt or sign, but that’s about what I relegate it to. How do people use those colors instead?Ĭobalt Blue just doesn’t seem different enough from other blues to be of value- it’s not dark like Ultramarine Blue, it’s not pale and hyper granulating like Cerulran Blue, it’s not a great green mixer like Cobalt Turquoise, it’s not a powerful non-granulating mixer like Prussian or Pthalo Blue. So, I’ve considered removing it from my palette, and getting perhaps a different blue on my palette instead- perhaps a Pthalo or Prussian. But Cobalt? Not sure why I have it there…. ![]() I like to mix Cobalt Turquiose with various yellows to make a variety of natural greens. I’ve even used Pthalo Blue for skies, but not really Cobalt Blue- it just seems so similar to UB I skip right over to it instead. Occasionally, if I want something with more violet, I use a very pale wash of Ult Blue instead- Cobalt just doesn’t seem violet enough. I use Ceruean blue for my skies pretty often, as I like the cool pale, granulating nature of it. ![]() Sometimes, I use Cobalt Blue as a cooling off tool, if my shadows get too purpley-brown, but just a touch of it. I go through Ult Blue like nobody’s business, as I use it as the primary darkening blue agent for shadows, etc. Do others here use it? And if so, how? And why use it, instead of another blue? If you don’t use it, what Blues do you use instead? As such, I’ve been pondering removing it, but it’s considered such an “essential” by many well known painters that I’ve paused a bit. I have Cobalt Blue on my palette but don’t really use it much.
