Fantastic Colour Explosion Postcard. 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, Colour Explosion Postcard 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 plotted on the card.
How Its Made
The concept of Krautfarben shows different approaches to handle the characteristics of the red cabbage. All approaches are based on the dye anthocyanin which is able to convert its colour to various different hues. Purple turns to shining pink or bright green – amazing colours you wouldn’t bring in conjunction with a natural colouring agent such as red cabbage. In time, the fresh, bright colours change to pastel shades, which at the end are to be distinguished as delicate shades of grey. The transience of the colours is a central theme of the Colour Explosion Postcard. To observe and to accept the moment of changing and aging demands sensitivity and understanding for the beauty of natural processes.
