THE CHEMISTRY OF NATURAL COLOURS
Silk screen posters printed with colours derived from vegetables and fruits. The visual reference of the project is the outcome of one discovery I did during my colour experiments; the fact that I could change the colour and appearence of some vegetables by adding acid or alkali. Red cabbage could turn pink or green in a split second, by adding vinegar or baking soda to the juice. This chemical reaction more or less tied the whole project together. The periodic table shows the colours, each with an individual number and information on which mordant or acid/alkali added to it. The hexagon posters are visually inspired by chemical formulas and the CMYK-circle, and demonstrates how the colours blend together. In the bottom right corner of each poster there is information about which colours that have been used and what number they have in the periodic table. My dogma: All additives (thickeners and mordants) should be found in a kitchen.
