In her studio in Wakefield’s Art House, down in the southern corner of Yorkshire’s Rhubarb Triangle, textile artist Kirstie Williams is checking out the possibilities of rhubarb root as a natural dye.
She creates swatches using traditional dyestuffs, such as oak bark, madder root and marigold heads, but recently she’s also experimented with avocado.
Rhubarb root gives a buff orange dye, a colour described by Scottish painter Patrick Syme in his 1821 version of Werner’s Nomenclature of Colours as resembling the ‘Streak from the Eye of the King Fisher.’
Rhubarb & Iron
Kirstie found that adding an iron mordant resulted in a deeper brown, described by Syme as a Reddish Orange, resembling the ‘Lower Wings of the Tyger Moth.’
A mordant combines with the dye and helps it adhere to material.
On the Farrow & Ball colour chart, I’d go for Fowler Pink and Red Earth as nearest matches to the rhubarb root dye, without and with the iron mordant.
In the Winsor & Newton range of watercolours the nearest to Syme’s Buff Orange is Naples Yellow Deep and his Reddish Orange is equivalent to their Brown Ochre.
I wouldn’t want too many earthy colours in my watercolour box, it can get confusing. I’ve tried to mix something similar from yellow ochre and sepia, but the colour hasn’t caught the character of Kirstie’s experiments.
Soda Ash
Kirstie’s Soda Ash modified rhubarb dye is something close to Farrow & Ball’s Calamine.
I wondered what my studio might look like if I went for one of these rhubarb-themed colours:
Thanks to Farrow & Ball’s AI-generated ability to try it on a photograph of your own room, I can try out the effect without committing myself. For a studio I’ll stick to white, but I’d quite like Red Earth for an old-fashioned study or library.
