Even the earliest cultures recognised, that all life in the end is dependent on the light of the sun. And as I was writing the first version of this article, an interesting thought came to my mind:
Life is consisting of blue water and yellow sunlight. If we mix the colours yellow and blue, the result is green:
The colour of life itself.
However, for thousands of years, yellow was known as the colour of the gods of the sun.
And the colour of wealth and prosperity as well, for yellow may replace gold in the symbolism of colours. So for example, yellow is the colour of the royal dynasty of Thailand, as well as the emperors of China.
Yellow in Europe
From medieval times until the 20th century, yellow was sometimes connected to a negative context, as a colour of greed, jealousy and envy. In the catholic liturgical colours, there is no yellow present. Perhaps because there is more than enough blood-soaked gold decorating their churches.
In the 3rd Reich, Jews had to wear a yellow badge, sewed on their outer garments in order to mark them as Jews in public. Yellow used to be the colour of discrimination in Europe since medieval times.
In English, you turn “green with envy”, in German you turn yellow (Gelb vor Neid werden).
Yellow in the spectrum
Yellow covers a very small part of the visible spectrum of colours. That´s why yellow with just a little red appears as orange, while just small amounts of blue added, and it turns out as greenish colour.
Thus, designers or artists add small portions of red/blue innately, to let the colour appear warm or cold, despite the colour of light in a room for example.
The range of true yellow, often called neutral yellow, is quite small.
Yellow as signal colour
Right after red, yellow is the most common signal colour. Thinking of yellow traffic lights, yellow danger signs or the yellow signal flags aboard a ship.
The connection between the colour yellow and yelling is no coincidence, because as a signal colour, yellow is yelling. Also the popular press, telling a heap load of crap, is often called yellow press (interesting… let´s cite that phrase from above again: yellow is the colour of the sun).
