I love receiving emails from readers and especially when they send me information that I might find interesting. Last week a reader sent me the following quote by John Lovett (an Australian watercolorist, whose work and teaching I love).
French Ultramarine Blue: Warm Blue, tending towards violet, so contains some red. Non-staining and sedimentary, so will lift off easily. Built up washes will clog paper texture after 3-4 layers, after which pigment will tend to lift off. French Ultramarine is a higher series than plain Ultramarine, so is more expensive. It is however, a much stronger pigment and will out last 2 tubes of plain Ultramarine, so in the long run is better value and much better to use.
This is John Lovett’s website here and I note that he doesn’t include Daniel Smith in the list of brands for this colour. Maybe this is the case with some other, but I have not found a difference between DS Ultramarine Blue and DS French Ultramarine in quality.
The main reason for my choice of Ultramarine over French is that it makes better green. I am very grateful to my great friend Jane Blundell for first telling me this. At the Daniel Smith event we attended last year, John Coglan mentioned the difference between the two versions: French Ultramarine has a bigger particle size and is warmer (redder) than Ultramarine Blue.
But I thought it was worth testing again and that is what I did. The slightly warmer (redder) hue of French was noticeable but I couldn’t see much difference in the mixed purples.
However, I did notice a difference in the greens. I’m not sure to what degree you can see this but the Ultramarine Blue is brighter and more lively and this variation is important for me. I am not super sensitive when it comes to subtle variations in purple hues, but getting good greens is more of a big deal for me.
In conclusion, there is not a lot of difference between the two from my tests and usage so I am happy to stick with Ultramarine Blue. But as always, I would love to hear from you, if you have found differently, or simply just to share which version or brand of Ultramarine you use.
And just finally: you might want to check out Jane Blundell’s amazing blogpost about the pigment.
