Red shoe soles are protectable as a trade mark. This was declared by the European Court of Justice in Luxembourg (C-163/16). Background: the manufacturer Christian Louboutin had registered them as a trade mark in Belgium, the Netherlands and Luxembourg in 2010 in the shade Pantone 18663TP and now sued the Dutch Deichmann subsidiary Van Haren, which also marketed shoes with red soles. Van Haren argued in court that colour was part of the non-protectable shape, but did not prevail. A Dutch court will now decide whether Van Haren has to take the red shoes off the market and is liable for damages.
A brief internet search reveals that not only in Europe do Nivea, Langenscheidt, Milka, Telekom and others "protect their respective colours from imitation", but important colour trademarks also come from the United States: Tiffany (light turquoise), 3M-PostIt (yellow), UPS (brown) and JohnDeere (green/yellow) are also well-known examples in our country. The respective colours may not be used by any competing company for similar products.

Comment: The commercialisation of our sensations is progressing, after all, colour is nothing but a sensation within us. When will pain, anger, sadness and other feelings become protectable, when will we have to pay royalties to Hollywood for love? Thoughts are free, as the saying goes - we should remember that.
