So, why does a rainbow have only seven colors? These colors form a visual spectrum, meaning each color blends into the next so there are no actual distinct colors. When these colors pass through the prism, they will bend or refract at different angles, which is what causes the rainbow of colors visible to the eye. On the other hand, you have red, which has a long wavelength of 700 nanometers. All colors have wavelengths, which can be measured in nanometers, for example, violet has a short wavelength of 380 nanometers. These colors are visible to the naked eye and are part of what is known as the visible light spectrum. This proved white light is composed of a vast spectrum of colors. When white light moves through a prism, the light refracts and produces various colors. Another famous scientist, Sir Isaac Newton, also contributed to this research with his glass prism experiment, which explained the breakdown of white light. The first person or philosopher to describe light reflections and refraction in the 17th century was René Descartes. 3.3 Do You Get a Rainbow Without Colors?Ī rainbow may be a little more complex than a simple colorful arc.3.2 What Are the Colors of the Rainbow?.Incidentally, the purple areas also more or less coincide with the land that will be flooded when all the polar ice caps melt. That there are a few big potholes in Asia: areas that are much lower than all the land around it. That the west side of the Arab Peninsula is much higher than the east side. And that the Sahara is not a boring plain but has some interesting mountain ranges. For example, I had never realized that a large part of southern Africa is quite high. In any case, it contributes to my knowledge. In addition, the map contributes to our knowledge of the relief on our planet. Proportional and weighted distribution ReliefĪpart from the idealistic aspects, I also think the colors are just beautiful to look at. I have therefore moved several sliders a bit to the left to prevent the blue and purple from predominating. Really high eleveations are rare on our world. From purple for the lowlands, to red for the highest mountains. I have “translated” the shades of gray on the elevation map of our planet into the six colors of the Pride flag. What do you do, in that case, as a cartographer? Make a world map, of course. Since I have some affinity with the b in lgbti, I felt the strong need to make a statement between matches. From shades of gray to rainbow colors World map In the rest of the world, too, many people still believe they have the right to determine how others organize their lives. But it would be silly to blame only the Qataris. Yet Qatar did not want rainbows or other expressions of diversity in the stadiums.
#RAINBOW COLORS SKIN#
But the idea is the same: the right of everyone to be themselves, regardless of skin color, descent, sexual preference or gender. Not really rainbow colors, and certainly not in that order. The OneLove band that fifa banned during the World Cup has another color combination: red, black, green, pink, yellow and blue. Rainbow flags during Rotterdam Pride OneLove For practical reasons, the six that are used today remained: red, orange, yellow, green, blue and purple. The Pride flag was designed by the American artist Gilbert Baker it originally had eight colors. Since the late 1970s, the rainbow has mainly been associated with the struggle of gays, lesbians, transgenders and related groups for equality. A few decades ago there were a lot of car stickers with the colorful arc and the words “there is hope”. Interestingly, the rainbow was also used as a symbol by evangelical Christians for a while. Over the centuries, rainbow flags have therefore been used by very diverse groups: Incas, Basques, Greenpeace, German farmers in the 16th century, the peace movement. It is a beautiful yet harmless natural phenomenon that is also somewhat rare and fleeting. It’s quite logical that rainbows have always appealed to people’s imagination. A world map in rainbow colors Rainbow flags And of the organizing committee that banned every piece of textile with rainbow colors from the stadiums. That was of course mainly the fault of Fifa, which banned “political” expressions such as the OneLove band under penalty of a yellow card. A tournament that quickly degenerated into a statement contest. The rainbow world map I present in this blog post is a direct result of the World Cup in Qatar.
