Once found and selected, Busch goes about animating the images in the studio. Asked as to which colour he needs to buy most regularly, the painter answers, “White. I actually only use white, never black.” Busch mixes all of his colours – primarily blues and greens – with white. White is what lends the pictures a sense of transience. White serves to weaken and break up the starkness of the hues and colours, neutralising severe contrasts. White drapes itself over the image like a veil, while also lending it an illusion of the sublime. This serves to distance the observer from the image. The action appears removed. Resembling overexposed or faded photographs the light decomposes the information.
