This weeks colours are mainly produced by Ruth Siddall who says of them;
These slates and shales represent the Palaeozoic stratigraphy of north west England and Wales. The coal-black, black shale from Britannia Quarry in the Pennines and was collected during a field trip to the South Pennine Coalfied with Onya McCausland. The slates from Penrhyn (Cambrian Slate) and Blaenau Ffestiniog and the red shale from the shores of the Menai Straits were all collected in North Wales over the past year. I would like to dedicate this set of pigments to my late mother, Anne Siddall (8th June 1940-22nd November 2020) who grew up in Lancashire, the daughter of parents from North Wales and with ancestors who worked in the slate quarries of the region. The Plas Brereton red ochre slate outcrops close to her final home in Caernarfon.
All colours are bound in gum Arabic on Winsor & Newton watercolour paper and read from left to right.
