Automobile Paint Design

I expanded my photo laboratory in the mid 1970s, when I developed successful recipes and processes to produce prints up to 40 x 50 cm in size directly from slides without inter-negatives. My specialties included film developments - color negative film and slides - as well as pseudo-solarizations in color.
I displayed color prints that I made out of pseudo-solarized film in 1976 at my first exhibition at the town hall in the city of Münster, Germany. This was followed by twelve more exhibitions (also in towns such as Orleans, France and Enschede, Netherland) with various motif groups.
My preoccupation with color photography (and with the laws of color) was a good basis for starting up with automobile paint design. Since the refinishing paint can no longer be recognized once damage to an automobile has been repaired (that's the prerequisite for a successful repair), I had the idea of making targeted use of refinishing paint to style vehicles.
I gave this styling and technique the name "Autolackdesign" (automobile painting design) and, at the end of the 1980s, I wrote a book about it under the same title.

Complete styling of my first Golf: I primed the car with a white primer, placed a white pearlescent paint on top of it and then added two layers of clear coat. I taped up the stripes on the transparent varnish, painted the surfaces with a shaded primer and then with the colored pearlescent paint. I then added up to eight coats of clear coat with some intermediate sanding to give the effect that all the color stripes appear to be embedded in glass. This work took almost three months to complete.

This "Sun King" was the first of three models: The first Sun King (to the right in the photo) had color stripes that started on the rear right corner of the roof and ran towards the front left side. The second "Sun King" (shown in the middle of the photo) had the "sun" on the right side of the car, such that the driver's side of this Sun King was white.
The third "Sun King" was the brightest. It had the sun at the bottom of the driver's side and the color stripes proceeded across the entire vehicle (to the left in the photo).

aurum magicum

At the end of the 1980s, I came up with the idea of using new combination pigments (interference pigments featuring mica carriers and titanium dioxide/iron oxide layering) to create a golden paint. I selected one of 12 trial batches and baptized it with the lovely Latin name "aurum magicum". Its color and brilliance put it ahead of all of the other gold paints.
When compared to a vehicle painted with real gold powder, all of the testers were of the opinion that it was my Golf that had the genuine gold. I had not only "invented" gold, but had also succeeded in creating pale gold and rose gold all in one.
Eventually I sold the license to manufacture "aurum magicum" to the Wuppertal coating manufacturer Herberts, which offered the paint color in the refinishing program featured by Standox.

Where the rainbow ends is where the "aurum magicum" begins!

Tailor-Made OEM-colors

People should talk about paints and be able to recognize them! With this in mind, I created three OEM series paints for Volkswagen at the end the 1980s: "Golf Green" was and is the most noticeable series paint color, since its maximum reflection lies at the same wavelength as the maximum reflection of the sensitivity of our human eyes. "Golf Red" is the reddest shade of red in the series. "Golf Blue" completes the threesome.

"Mars Red" is on the left-hand side of the picture and is more yellow than "Golf Red", while "Verkehrs Purple" to the right is more blue than "Golf Red", which is the reddest red!
And where is the yellow in this trio? Stylistically speaking, a strong yellow would not fit well with these three Golf colors. And there's no dark yellow to be seen. Brown and ocher are not dark yellow colors, but they are often suggested as alternatives. As such, we stuck with the creation of these three "Golf colors"!

---

For my white Golf I had at the end (before it was completely repainted) 22 hoods, which I had designed differently. At the weekend I exchanged the hood on the car for another.

---

In addition to painting hoods and vehicles, for example, "barrel towers" were created from barrels stacked inside one another and painted differently. Or balls with interference pigments or dayglow paints.

---

These photos show the first tests with interference pigments (then also called pearlescent pigments), which were carried out in the second half of the 1970s. The green ball with pearlescent red clearly shows the effect: close to the gloss, the red of the interference pigment appears; away from the gloss, the green color of the background can be seen through the transparent pigments.

---

The design of this hood and the car combines all the properties of the transparent interference pigments: The car and the hood were first sprayed white. Then areas on the white surfaces were masked off and painted in black. Then the stripes were painted in different colors of the interference pigments. If one looks close to the gloss at the stripes over white and black backgrounds, one can clearly see the typical reflection color in each case. If one moves away from the gloss, the reflection color changes to the complementary transmission color. This is absorbed by the black background.
