"With the cycle "True colors: Blue, Red, Yellow, Green", Christina Mitterhuber picks up the theory of primary colors. The perception researcher Ewald Hering has also spoken of primary colors and described their particular effect of the complementary colors blue-yellow and red-green. The artist Christina Mitterhuber confirms with emotional, spontaneous gestures, what scientists have found out in long studies: the intensification of color experience in the immediate interaction of the individual primary colors."
