How a blue leds changed the world

Where does my love for the color blue come from? Is there a genetic explanation for this? My first blue dress was jeans. Blue comes first when choosing the color of a car or glasses. My mother preferred to wear blue clothes. The farmers wore blue overalls, according to my most early memories.

“The color blue has no strong emotional value in the Netherlands, at most it stands for pure or pure. In English-speaking countries, however, blue is associated with melancholy or sadness, for example in the blues music style. Since the introduction of jeans, a lot of blue clothing has been worn.”  (Wiki)

A blue pigment changed the world.

However, it is the word blue that has developed diverse and sometimes quite unexpected associations in the Russian language. Traditionally, this color was a symbol of noble birth and the expression blue-blooded was used to describe members of the aristocracy.

In Soviet times, especially in the 1960s, blue became associated with the romance and excitement of exploring and developing remote parts of the country (one of the popular songs of the time, which urged young people to join construction projects in Siberia, was called “Blue cities”). The word blue was also used to describe far-reaching dreams and aspirations.

For the Empire-builders of old, the uncharted African inland area was the landscape of a dream in the making. A dream that would etch its course in parallel lines that snaked their way northward from the Atlantic shoreline, conquering the distance from Cape Town to Cairo.

In case we will win any meaningful lottery or will be respectfully rewarded by companies we worked for, we for sure will book for a trip by the ‘Blou Trein’.

Keep an eye on this: the link below still refers to the Dutch history … dot ZA … Zuid-Afrika. And the word ‘blou’ refers to the Dutch word ‘blauw’ …

Chefchaouen is a city in the northwest of Morocco. It is the chief town of the province of the same name, and is noted for its buildings in shades of blue.

Chefchaouen's blue walls are a popular subject of interest. There are several theories as to why the walls were painted blue. One popular theory is that the blue keeps mosquitos away. The blue is said to symbolize the sky and heaven, and serve as a reminder to lead a spiritual life. However, according to some locals, the walls were mandated to be painted blue simply to attract tourists at some point in the 1970s.

blauer Traktor


Today’s tractor paint colors identify which manufacturer made the machine, but it not always has been this simple. The common John Deere green is a more modern addition to the history of tractor paint colors. Tracing the origin of today’s tractor colors takes us back before the turn of the 20th century. Late 1800s shows most tractors being black, gray, and brow like, the Hart-Parr.

Speculation and guesses tell us that the paint used was sometimes surplus military paint. Other opinions focus on the more serious nature of the population and less time spent on frivolous extras.

Some people say the Jodhapur’s color is closely associated with the Brahmins and the blue houses of the old city which belong to families of that caste.

There’s also an argument residents struggled to get rid of the termites from their homes, repelled them and discouraged their return by adding chemicals like copper sulphate, to their standard whitewash.

Some even rubbish this theory and swear that Jodhpur is a fine example of an environmentally-friendly city. Nothing but indigo, a natural dye, is the cause of the blue tint, they say.

Ultimately there may be no evidence as to why the houses are blue. But, they are beautiful blue !
