Swatching and painting with YInMn Blue (PB86) (review)
YInMn Blue (PB86) is the first inorganic blue in over 200 years. It was discovered by chemist Dr. Mas Subramanian and his team in 2009 at Oregon State University. This pigment has since been exclusively licensed to and brought to commercialization by The Shepherd Color Company.
I was interested to check out this colour but it's incredibly expensive. There are many sellers on Etsy selling their handmade paint and half pans can cost around US $45 - $80. The price varies wildly. This is even more expensive than Lapis Lazuli.
YInMn Blue gets its name from Yttrium, Indium and Manganese Oxide. Yttrium and Indium are expensive hence YInMn Blue is expensive.
The half pan that I have is a sample from Alina Gallo. It's one of the colours included in the watercolour signature set 2 that she's selling. By the way, her products are always out of stock because they only stock once a month. At the time of this review, they don't sell YInMn Blue separately.
According Golden Artist Colours, the colour space of YInMn Blue is between Cobalt Blue Deep (PB74) and Ultramarine Blue (PB29). I made the mistake of using Cobalt Blue instead of Cobalt Blue Deep in the swatch above.
YInMn Blue is a granulating transparent blue. The tinting strength is good meaning you can achieve intensity with a bit of paint. I wasn't able to test the lightfastness of the paint though.
This is how YInMn Blue (PB86) compares to Cobalt Blue Deep (PB74). PB74, as the name suggest, has a deeper blue. I probably won't be able to tell the two apart without a side by side comparison. By the way, Cobalt Blue Deep is one of the most granulating watercolour paint.
Here's a sketch I painted with YInMn Blue.
YInMn Blue looks very similar to Cobalt Blue Deep and behaves the same. So there's no real reason to buy YInMn Blue when Cobalt Blue Deep is cheaper.
The intense granulating is lovely.
The green here was mixed with Nickel Azo Yellow PY150. This green looks like Sap Green or a green you can mix with Ultramarine.
You can get some nice colour separation with various mixtures.
YInMn Blue is a beautiful blue but since it looks so similar to Cobalt Blue Deep, there's no real reason to buy this over the latter especially when YInMn Blue is so expensive. And there are not many companies currently selling this colour commercially except for the few sellers on Etsy, and from Alina Gallo and Kremer Pigments.

Oto Kano who tested the
Oto Kano who tested the Kremer YimMn blue said that this particular paint dries cement hard after a couple of months into its pan. So if you want to enjoy it you've got to use it as soon as possible. Otherwise you will not be able to remove it from its pan.
Here is her video.

Thanks for the tip.
I wonder if it's the case of not having enough binder/honey.
I make my own watercolours
I make my own watercolours and I don't think that it has something to do with the amount of binder. The binder is Gum Arabic not the honey, glycerine, Ox Gall or whatever else manufacturers add in the mix.
Some pigments of course have the tendency to dry harder particularly the earth ones. Viridian also dries really hard and sometimes cracks if you don't add something like honey of glycerin to keep it more moist in the pans.
But even these kind of pigments rewet normally and load a decent amount of paint on your brush without that need to scrub with your brush.
The Kremer YinMn blue that Oto Kano tested didn't. It didn't look - at least to me - like a regular hard drying kind of paint as it didn't release any amount of colour on her brush and it looks at least on the video like hardened clay or something similar.
Whatever is the case with this colour I don't really see the point of paying that much money to switch to a blue paint that looks like a slightly more opaque version of a dark Cobalt Blue or an Ultramarine and that because it doesn't even offer something different on regard of its mixes with other colours.
Even the colour separation that you mention on your review is visible only from very close and not from distance.
If you need a magnifying glass ( or zoom lens) to figure out what is the difference... then there is no difference because nobody is going to notice it unless you tell them. lol
Do we know that Esty sellers
Do we know that Esty sellers are selling the actual pigment in their products? There was a NYC paint maker who sold "genuine" paints like Vermilion that were mixtures of organic pigments. He would even put grit into his Naples and Lead Tin fakes to make people think they were the real thing.
Do we know that the pigment
Do we know that the pigment is actually the only thing in Etsy sellers' products? There was a NYC paint maker who passed off organic pigments in his paints as expensive old pigment paints, like vermilion, Naples yellow, and lead-tin yellow. He would even add grit to the latter two to fool people. Buying from Kremer and making the paints by hand is the only way to be sure you're using the real thing, unless you send those Etsy samples to a lab for analysis.
