A Colour A Day: Week 28

Ruth Siddall4 October 2020

A Colour A Day; 28th  September – 4th October

Jo Volley writes…

This week’s colours are seven Russian earth pigments gifted by Ruth Siddall who says of them. ‘These seven pigments are supplied by Moscow-based company Colibri Premium Pigments. Many of the earth and mineral pigments they supply are sourced in Russia. This is a selection of their ochres, which include iron ochres (red and yellow ochre) and aluminium-rich earths known as bauxite (deposits much overlooked as ochres). Siderite is iron carbonate. Also included here are two very ‘Russian’ pigments made from minerals mainly known only from deposits in Russia. Shungite is a black, carbon-rich earth pigment. It is found in very ancient, 2 billion year old rocks in Russian Karelia, in the region of Lake Onega. It is named after the town of Shunga. It formed as biogenic deposits, probably from algae preserved in anoxic conditions and then subsequently metamorphosed. Volkonskoite is a green-coloured, chrome-bearing smectite clay mineral. It is sourced from the Okhansk region of the Urals. Tuff is a volcanic ash deposit, in this case coloured purple by iron oxides.

Ruth suggests listening to Sibelius’s Karelian Suite whilst viewing the colours.

All pigments are bound in gum Arabic on W&N watercolour paper and read from left to right:

This week we celebrate Goethe’s 271st birthday, 28th August, with earth pigments from Cyprus collected and processed by Ruth Siddall who says of them …

Cyprus is an island long associated with the production of pigments. These are by-products of the copper mining that has been active since the Bronze Age when Cyprus was the main supplier of copper ingots in the eastern Mediterranean region. But it was not copper-based pigments that were in abundance, it was the iron and manganese-rich ochres and umbers which were typical of Cyprus as well as the celadonite-rich green earth deposits. The Cypriot umber is a true umber in the geological sense having formed at a mid-ocean ridge plate tectonic boundary. In fact this is the environment of deposition of all of Cyprus’s ores and pigments. They originally formed in deep ocean waters, superheated by volcanic activity and then this slab of oceanic rock, ores and all, was emplaced onto the Eurasian continent during the construction of the Alpine mountain chain. The ochres formed by the weathering of the ores both before and after this emplacement onto dry land. Such a geological environment is uncommon, and Cyprus is by far the biggest example of these processes on Earth. A unique island for pigment formation.’

A COLOUR A DAY – Week 4 – 13th -19th April

Jo Volley writes …

For Week 4, here are 7 green earth pigments from various locations from around the world.

‘I kept putting the same colour on – the same colour, the same colour – but every time I put it on it was different. Each time it was this whole new light/colour experience. It was not a revelation, but a whole wonderful new experience… To me, it involves harnessing some of the powers of the earth. Harnessing and communicating.’  Brice Marden on terre vert
