Ochre is one of the oldest pigments used by humankind. Traces of its use date back nearly 300,000 years, long before the earliest cave paintings we know of, such as Lascaux. Its shades possess that unique beauty of being both warm and neutral, present without ever being overpowering. They ground us, rekindle memories of summer and prolong the light of those sunny days just a little longer, just as we start to dig out our winter coats and change the clocks. Our selection this week therefore features a palette ranging from yellow to orange – the colours of autumn leaves, harvests, parched earth and saffron.
