Prussian Blue PB27 Watercolor Comparison - Mijello - Schmincke - Da Vinci - Van Gogh 

I'm not sure if you already know this now but Prussian blue gets darker, not lighter when you put it out where sunlight reaches it. Once you put it back inside in a darker place it becomes lighter. I tested this myself with my Winsor newton, daniel smith, and Holbein, watercolors and it seemed to be true.

I really love this color in paint,but my favorite has to be the Daler Rowney acrylic ink version of it. I use that when I do not want my blue bleeding into brighter colors. I do not know how lightfast it is though. You are really making me fall in love with Davinci paints though!

They all look really nice and dark. I stopped using it after reading how it was replaced by pthalos but still love how it looks. I can't remember the source text, but I remember reading about the pigment being called a "cyanotype", meaning that it lightens when it is exposed to light but goes back to normal when it is stored in a dark place. I'd like to know more about it if someone is better informed XD

They passed my lightfast tests BUT I only tested 6 months (spring - early fall) in Canada. I feel it works if I’m selling original art in Canada. I’ll mention ‘recharging’ if fading is noticed after many years for wall hanging framed art. I hear now I should do a full year? I’ll have to continue my new tests longer and redo my older ones I suppose. I tested the Van Gogh and the HimI/Miya gouache. I think art put behind UV protective glass would last even longer as well. Still if you are selling artwork lightfastness is important. But for sketchbooks, scanning, or yourself it’s not. I also use very not lightfast supplies for wall hanging art. If it fades I take it down and replace it with new art! I often take it down more often that that and put new art up in that spot anyways. Photograph and scan the art right away then back up the files in an external hard drive. I fell knowing the lightfast properties is valuable BUT being scared to use beautiful colours you love is harmful! I have been enjoying neon watercolour and gouache lately it allows me to actually get the proper colour for certain flowers, birds and fish, etc. and it is better to me even knowing it will fade. It’s all fragile paper and destroyed by a too large splash of water anyway. Let’s use the paint we feel a connection too even if it’s not lightfast. Just remember and categorize, and double check for original commissions.

Your swatching videos are so nice and relaxing I really enjoy when you include the wetting of the soon to be swatched area it just adds a little effect. I can also experience new/different paints to me and learn a few things. Have a great day

This was the first Blue I fell in love with. Mix it with Quinacridone Violet PV19 for a good Indigo.

My prussian blue fell down the sink last month... i cant moven on 😭💔

It was the first blue I fell in love with, too. I only have Van Gogh PB and by seeing it side by side with 3 artist-grade brands, I don't think it disappointed at all. 💪 Da Vinci, on the other hand... Thanks, Jay! 🙌

It's easy to understand why the invention of this pigment changed the entire art world! So nice to have lunch with a new swatching video from you. Hope you are well. PS: I want to do a lightfast test on my Prussians, including several brands. I am hopeful about the Qor. Plus I want to see that weird effect of the darkness reversing it!

Prussian Blue is one of my favourite colours. I use Winsor & Newton. I heard that the name change came about due to "politically correct" verbiage. Prussian Blue was the colour of the Military in Prussia so to neutralize any stigma they changed the colour.

4:07 Wow - that drying shift! This answers the question I had after swatching the Schmincke dotcard, which was, is their Prussian Blue really that light? And it is! Schmincke and Mjello really do have a much greener undertone, which I like. The DaVinci went down smooth as glass!

I love this color and I hate that it's not lightfast. I have Daniel Smith's Prussian Blue which is moody and rich. I should do a painting with it and Opera just because. I find that my DaVinci Pthalo Blue RS does come close but it's brighter and has a higher chroma and I find I can make a hue with it. Also, DaVinci's Indigo is Prussian Blue and a Quin Violet and it's really beautiful.

phtalo blue is very staining and therefor not for every technique or style. an alternative to prussian blue should rather be a colour, that schmincke calls parisian blue. I could go to my schmincke card flyer and look up the pigment number - but I confess, I am a bit lazy right now :-D sorry

Prussian Blue has always been my favourite blue, and that stayed the same when I switched to learning watercolours. Since I'm still learning I've just been using a student grade brand (Staedtler) but I have a Daniel Smith Prussian Blue waiting for when I get more skilled.

Thanks for swatching the Prussian Blue. I prefer this to pthalo blue as I find it too strong and greens mixed with it turn out too bright. This is my go to cool blue.

The Da Vinci looks closer in darkness to my favorite WN prussian blue, which is still much darker. This is the only paint of theirs that has poured thick and lumpy for me though. It rewets easily and is by far my favorite. I dont think the first 3 reach the dark navy depth that Im used to, but they are all lovely. TFS 😊

Daniel Smith is best.

Prussian Blue is gorgeous in my opinion. My first set was the Van Gogh travel palette (12 + 3) which contained Prussian Blue - 508. I also have a Kuretake Prussian Blue, which is marginally darker, and Winsor & Newton Prussian Blue which is my favourite for it's transparency and rich hue that make it great for mixing as a primary blue. It has the highest lightfastness rating, according to W&N, and can be used to mix with Burnt Umber for a beautuful black. It's a powerful, so go steady when mixing it. Your swatching comparison is excellent, as always. Of the four here, I'm leaning towards the Schmincke Horadam.

I have Blockx, M.Graham and DS. I love them all. I cannot live without Prussian Blue 🤣

I've done lightfastness tests on a few of my Prussian Blues, plus some mixes that contain PB27. Unfortunately, it does fade quite severely in each case. I have not tried to reconstitute it, though, but I have heard of it. Maybe I'll try it. I do love the shade, but will only use it and the convenience mixes for sketchbook work.

I real love Prussian blue however keep a lot of blues on my 33 well palette and their always seems a better blue to reach for in most circumstances, and I will probably trade it out in the future for a PB 60 blue. That said I do a lot of monochromatic landscapes and it's a really beautiful color in that circumstance. In a limited palette it probably wouldn't be included however.

I'm a sucker for Prussian Blue. I use it a lot to mix with my greens, but I don't use it for commission work, so the lightfast doesn't affect me, but yeah I do love those Prussian Blues.

it's.... it's.... DARK... magic! 555555555 but yeah, that's quite insane that it regains saturation in the dark. so funny~

Well, my fav is the Da Vinci XD It seems more velvety and more unique compared to phtalo blue. Also it would make a great single pigment indigo version ;) (too bad I can't get the da vinci from spain...)

I love the most in this swatches is mijello and da vinci..... I have this BERKELEY, a student grade watercolor who happened to be much the same with this colors..... Dark kind of blue.... I love this blue so much and i have this on my palette. I use this on making dark details on trees. Substitute to dark earth colors and black... Making a very dark green shade using this color....

I don’t own one. I’ll stick to my favorite phthalo blue by DV or DS

I don't have Prussian Blue in my palette because I heard the same story. I would choose the Da Vinci because I prefer muted colors. Just not into brights.

Heyyyy new video wootwoot! I was just thinking about you the other day when I got to swatch out my new Paynes grey! 😂

I'm a beginner and I have Sennelier Prussian Blue in my palette (professional grade). Mainly WN, Daniel Smith & Holbein. I just love the rich and vibrant color... also how it plays on my Arches, which I just began to use. Didn't do a lightfast test... a very beginner I'm just happy to paint and practice. Thank you!!!

I like how Prussian blue mixes. It gives a nice a dark tone that can substituted for black when mixed with burnt umber and I like the effects you get when mixing it directly on the paper with burnt sienna. I just like the colour. since O mostly wirk in my sketchbook with water colours it not exposed to that much light.

i think mission gold and schmincke are the most green also? (i'm sure the camera alters a bit, but from here i believe that's what i'm seeing.). still would like to see someone do a vid showing PB27 and THEN also i guess the phthalo blues to show what a good dupe would be. : )

Bought this colour a bit on a whim, needed a few colours that were running out, and decided to add this one. It's from Lukas the 1862 range, so not one of these. Will make a swatch later today.

Although I’ve several blues when I’m not trying to do anything particular or colour match something, my hand automatically goes to Prussian blue. That explains how much I’m in love with it, subconsciously!

I love Prussian blue, I prefer it to phthalo blue. But I haven't tested mine for lightfastness yet, so it's all sketchbook work at the moment. I have the Van Gogh and the Schmincke versions, with the Van Gogh one being the one I use the most. I loved seeing these next to each other

I looove prussian blue for mixing skintones

Prussian Blue PB27 can go from permanent to impermanent even in the same brands depending on the batch number. So, its best to light fast test every one before using no matter what brand. My Winser & Newton PB27 in both Prussian and Antwerp blue tested very lightfast 7 months in south facing window during longest daylight months of the year. But people who had this pigment in the same brand bought at a different time with different batch, came out quit fugitive. M Graham was suppose to have tested very lightfast with some and others found it fading, so you never know. I cannot seem to enjoy using this pigment because it looks a bit dirty to my eye compared to Phthalo Blue's.

I use the Van Gogh Prussian Blue but the quality is not good. The pan does not rewet easily and the paint usually contains visible pigment particles 😕. I have to scrub at it with a cheap brush to get any colour. The colour is weak but nice. Does anyone else have this problem?
