Nicholson and Kate spent two weeks on Eigg in May 1980, accompanied at first by the artist Donald Wilkinson and his family and secondly by the artists Valerie Thornton and Michael Chase. This time she stayed in the Gamekeeper’s Cottage.
As Alice Strang has explained:
‘The Gamekeeper’s Cottage is the highest house on the island, with panoramic views across the sea to the mainland. Due to the atmospheric conditions in the area, rainbows occur there with unusual frequency. From an early age Winifred had been fascinated by them, as they were a natural display of the splitting of light into the colour spectrum.’
(Strang, op.cit., p.50)
This phenomenon is celebrated in Rhododendrons, Eigg. A painting infused with colour and joy, it was created with the aid of a prism that Nicholson had recently acquired. Her series of prismatic paintings, of which Rhododendrons, Eigg is one of the finest, were extremely important to the artist.
Her grandson, Jovan Nicholson has explained, quoting her:
‘The way Winifred used a prism is straightforward: when you look through a prism the objects you see are rimmed with rainbow colours. “[My] prism is in a back pocket in my purse. I can put my hand into my pocket and pull it out whenever I want to see a rainbow. For the prism shows us rainbows everywhere.” She valued her prism as “a very little pot of gold”, for she “found out what flowers know, how to divide the colours as prisms do, onto longer and shorter wavelengths, and in so doing giving the luminosity and brilliance of pure colours…in the ordered sequence of the octave of colour.”’
(Jovan Nicholson, Winifred Nicholson: Liberation of Colour, Philip Wilson Publishers, London, 2016, p.32)
Moreover, Nicholson was drawn to paint flowers for much of her career, partly as a way to explore her theory that ‘colour is not just a coat over objects – it lies on the rim of objects between one form and the neighbouring form or space.’ (quoted in Judith Collins, Winifred Nicholson, The Tate Gallery, London, 1987, p.31).
She sensed that flowers:
‘…create colours out of the light of the sun, refracted by the rainbow prism…The flowers are sparks of light, built of and thrown out into the air as rainbows are thrown, in an arc…My paint brush always gives a tremor of pleasure when I let it paint a flower…to me they are the secret of the cosmos.’
(quoted in ed. Andrew Nicholson, Winifred Nicholson: Unknown Colour, Faber & Faber, London, 1987, pp.239 & 216)
