Jo Galloway was interested in making dyes and paints from biological sources. Jo Galloway found a recipe for natural paint that used soap along with some veg as she lacked some colours she also decided to use some natural food dyes. Jo Leng made only one colour of paint, green. She used spinach for this but found that she need to dry the spinach in order to get a strong colour. She spinach as sometimes she eats green pasta! Andy just brought some boiled beetroot and used the liquid that come off that.
