A fundamental classic and very beautiful, just look at the swatch opposite for a minute or so.
Loved by landscape painters, it is easy to control having the subtle tinting power of Cobalt. Greyer than Ultramarine, it possesses subtle hues which aren't found in the other blues.
Officially discovered in 1802, it had been used previously for many hundreds of years in the innovative and secret world of Chinese porcelain. From the excellent Handprint website;
"Cobalt pigments are the "cadmiums of cool," creating hues across the cool part of the colour circle from violet through blue to green, in the same way that cadmium hues extend across the warm colors from yellow through orange to red. This is because cobalt oxide can crystallize with several other common metals (aluminum, titanium, chromium, nickel, zinc, and tin) to produce a broad range of pigment colors that vary in both hue and lightness."
This is a very pure version with a gentle hint of warmth.

The cobalt blue is fabulous!
order arrived quickly and the quality of the products is excellent
I have always been sceptical of cobalt blue as a colour. In watercolours and acrylics it always seems to possess a muted grey cast without vibrancy. As a recent (very late) convert to oil colours I was more than impressed with the Langridge cobalt blue since it has a clarity of hue that I haven't experienced before. It seems my search for a true mid-range blue that is bereft of either a distinct greenish or purpleish cast is over. I am a convert to quality brands (such as Langridge) and I am very happy with the four tubes from this manufacturer that I have recently bought.
Don't use these paints if you want to blame the poor quality of your work on the materials as they are excellent!
