True Blue: The Monopolization Of Color And Why Using Another Brand’s Color Could Paint You Into A Legal Corner
I encountered an incredibly moving piece of art in the private collection of a family friend. It was beautiful, but even more than that, it took my breath away with its unbelievable color. Take a look:
The creator was French artist Yves Klein, who died in 1962 at the age of 34. Klein’s short time on the worldwide artistic stage brought him notoriety or his work in many diverse media, but his legacy is by far most noted for the iconic blue of his monochromatic blue art, such as that of the above sculpture.
As the story goes, Klein was so taken with the indescribable blue of the sky over the Mediterranean in Nice, France, that he dedicated his artistic talent developing a blue that would imbue the canvas with this color in its purest form. In fits and starts, he experimented with ultramarine and various resins and solvents, developing hues that would inevitably disappoint as they dried.
In 1960, he hit his mark, landing on a blue so extraordinary that he sought legal protection by submitting a notice claiming inventorship with the French government. He also obtained two French patents for the process of using human bodies to apply the paint to articles. Beyond the life of the patents and the formula, the color remains exclusively known by the proprietary trademarks “International Klein Blue,” or “IKB.” In the U.S. alone, there are several active trademark registrations for the marks YVES KLEIN and for IKB.
Also known for his performative art, Klein underscored his association with his signature blue with a release of 1001 blue helium balloons to mark a solo exhibit in Paris.
Artists still use IP law to thwart copycats of certain colors. Artists Stuart Semple and Anish Kapoor have been feuding in just such a fashion. When Kapoor purchased the rights to a material called “Vanta Black”, many artists including Semple desired to use it. Kapoor however, has decided to keep Vanta Black exclusively his own. Vanta Black’s unique properties cause it to absorb more than 99% of the light hitting it, making it potentially the blackest substance possible. In retaliation, Semple has allowed anyone but Kapoor to utilize the many colors Semple has himself invented, in an attempt to leverage Kapoor into sharing. So far, to no avail.
Many companies have established trademark protection in the color of their goods. Provided the color does not serve a functional purpose (such as bright yellow for safety gear), trademark protection may be available, upon a strong showing of public association between the goods and the color. T-Mobile has successfully protected magenta. Tiffany’s has its well-known baby blue, and UPS owns brown. Mattel has thus far been unsuccessful in obtaining trademark registration for its distinctive pink/magenta hue but aggressively polices against infringers through its common-law rights. .
As unique colors go, researchers have uncovered a previously unknown color, dubbed olo, thus far seen by only five people. The color can only be experienced through a laboratory procedure involving shooting laser pulses into the subjects’ eyeballs, causing the subjects to experience a pure, teal green saturation. The laser pulses only trigger one type out of the three types of cones in the patient’s eyes. This causes them to experience the color in the purest form that human sense of sight allows, not unlike the vibrance of the blue that Yves Klein sought to discover.
Colors play an important role in the toolbox of intellectual property assets. Conversely, caution should be used when approaching too close to the look belonging to a third party.
