Fantastic Colour Explosion
It seems to be a white postcard, but painted with the juice of red cabbage a multicoloured pattern appears. The developing phase of the colour takes its time and during the drying process the colours get gradually more intense. Out of this technique, a postcard set was developed. A set consists of a postcard that was screen printed with clear liquid, a packet of red cabbage powder, which is to be dissolved in water and a sponge, so that the coloured liquid can be coated on the card.
