title. Natural Colours 

date. March - October 2016

city. Ho Chi Minh

​

My childhood interest in natural colours intensified as I started researching into Vietnam's ancient art of woodblock printing in order to make a DIY woodblock printmaking kit. I wanted to know how artisans came up with five signature colours: brownish red, green, yellow, white and black, using only naturally obtained materials. Apart from investigating traditional sources of natural dyes used by printmaking artisans in Dong Ho village, I also experimented with edible and medicinal plants, hoping to identify new pigments that could be incorporated into my kit.

​

The process of extracting colours from those plants include boiling, straining and spray-drying. I found lá cẩm (Peristrophe roxburghiana), a plant traditionally used only for colouring rice, to be an abundant and stable source of violet pigment.
