Dark socks keep your feet warmer

Sunday evening on Breisacher Strasse in Haidhausen: In a back room, six people are sitting at a table with a large lamp hanging over it. No, people don't play poker. They eat and drink wine, and whenever a woman presses a button, the light of the lamp changes. Then the others take a sip of wine and are amazed: the wine tastes different when it is green than when it is red. Or blue.

The so-called light week with 45 events is currently running in Munich. "All are fully booked," says Nils-Peter Hey from Richard Pflaum Verlag, who runs the Lichtwoche with its specialist magazine light organized. There are specialist lectures, there are large events such as the light ride at the airport, during which the lighting technology of the runway was examined; but there are also small events like wine tasting.

Elisabeth Schiller is a master optician and light and color therapist. The wine tasting takes place in the back room of her shop in Haidhausen, and she is the woman who changes the light of the lamp at the push of a button. "It's a medical light like the one used by dermatologists or dentists," she says, pouring white wine for people. You drink in white light. Schiller presses the button, the color of the lamp changes to red. People are drinking again - and are surprised and apparently immediately convinced. "It tastes sour!" Shouts a woman. The others nod.

Why does it taste more sour?

"Red has a particular effect on us, the metabolism increases by 13 percent," says Elisabeth Schiller. That affects the taste. People talk confused; everyone knows something about red and its effect. Schiller says that those who wear red socks have warmer feet; or that you can make people collapse in a red room because the cycle is getting faster and faster; or that athletes with red jerseys would win more often - which finally reveals the secret of why FC Bayern is at the top in the Bundesliga and only in the regional league in 1860. "Blue is not that aggressive," says Schiller. "With light blue everything goes down in the body." In fact, the wine is sweeter when the light is blue.

The evening progresses, people then drink red wine and see that the play of colors works here too ("it tastes more oily", "now the wine is more velvety"). Elisabeth Schiller explains that people bring their senses together, so to speak, drink their eyes with them. "If we were to blindfold our eyes, we wouldn't even notice whether it was red or white wine." People eat and talk and nobody notices that the hours are passing by. "The expectations were met and exceeded," says one participant.

Monday evening in Lazarettstrasse in Neuhausen. Around 30 people sit in a container room at Pflaum Verlag and look at a screen with colorful letters. Christian Seiche, head of the Guerrilla Ligthing group, explains to the participants what they should do outside in the courtyard: Draw letters in the air by swinging searchlights. "The letters are mirrored and they mustn't be too small," said Seiche, "they have to be the size of a person, so you have to do a little evening gymnastics." Then the participants stand in front of the container with their headlights. The photographer Ingo Sebastian is about ten meters in front of them. As they swivel their headlights in the form of letters, a word appears on Sebastian's camera, "office" for example.

"You can do that with long exposure," he explains, "you have as long panning as the exposure is running." A normal camera has a few seconds, but Sebastian has a special camera with live composite technology - the exposure continues as long as the battery lasts.

After "office" they now paint "kindergarten" in the air. More letters, more people, more mistakes. "The K has to get bigger," Seiche shouts into the night, "and the R is out of line." - "The R has a back," says the man who paints the R with the headlight. "That's how it looks," replies Seiche. Everybody is laughing.

Guerrilla Lighting, a loose group of activists, wants to draw attention to grievances by highlighting them, so to speak. The words in front of the container are intended to show that more and more facilities are being housed in containers: offices, kindergartens, but also refugee homes and schools. They intentionally write "Schuhle" with an "h". Seiche smiles. "There are also grievances in Germany when it comes to education," he says.
