By the way, I'm currently using French Ultramarine. It's really difficult to see any difference between Ultramarine Blue and French Ultramarine , straight from the tube and also from the resulting colour mixtures. Here's what Daniel Smith say about Ultramarine Blue on their website :. Ultramarine Blue plots cooler and bluer than the more saturated French Ultramarine. Temperature aside, both blues have equal permanence, lightfastness and transparency. Ultramarine Blue is slightly less granular in concentrated washes.
For less saturation, sedimentation and cost, use Ultramarine Blue straight, for vibrant crayon-like color or mixed with a cool red for dark, effective neutrals. This medium-to-dark warm reddish-blue is highly lightfast and of medium tinting strength. Its sedimentary quality increases its versatility. Mixed with various portions of other blues, French Ultramarine is a wonderful sky pigment. Modify it with Quinacridone Gold for delightful greens that remain color-coordinated.
Mix French Ultramarine with Quinacridone Burnt Orange and be rewarded with an amazing range of blue to brown grays. Mixed with either Quinacridone Rose or Pink, a range of purples result. For another important mix, see Hooker's and Sap Green. 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 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. 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. However, I did notice a difference in the greens. 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. You are commenting using your Facebook account.

French Ultramarine Blue Two French chemists discovered some blue residue in a soda furnace one day and wondered if this could be developed into a blue paint to replace the costly ultramarine pigment. French Ultramarine and Ultramarine are really no different! Rate this:. Share this: Email Print. Like this: Like Loading Next Art Club or Art Class?
