water colour3636A water colour is made from Gum arabic dissolved in water in which the pigments havebeen very finely ground. The finer the pigment, the more transparent the colour. In theorywater colour can be used to paint on any type of paper, although the best results areachieved by using water colour paper. Water colour paper has a special surface sizing,usually of gelatine. This sizing ensures that the pigment is not absorbed by the paperso that the colours remain pure. What’s more, the sizing helps to prevent the paper fromcockling too much when a lot of water is used. When painting the colours are thinned withwater on a mixing tray and if desired mixed with one another.water colour
