Description
Backbarrow Blue was a grade of ultramarine pigment produced at Backbarrow near Windermere until the 1970s, also known as ‘dolly blue’, this paint is made from that exact pigment.
The most luminous ultramarine blue I have ever seen.
It also has that wonderful depth which all well-ground Ultramarine pigments have due to their semi-transparent nature, this particular pigment really bounces back a lot of blue light!
Leaning more towards violet than green on the colour wheel, the violet edge really vibrates when used thickly, as it is spread more thinly it approaches a more mid-blue.
The tints when white are added are excellent sky blues, the violet element really giving that UV feel of a summer sky.
It is smooth in handling and it has high pigment load.
