The color of sunlight is white, as the sun radiates all the colors of the rainbow, or more or less of these colors, and in physics, this mixture of colors is called white light, for this reason, many colors in the world can be seen by sunlight, if the sun's rays were green Everything will look green, or dark, while the redness of a rose, or the blue color of a butterfly's wing, for example, can be seen under the sun; Because sunlight contains red and blue light, the same applies to the rest of the other colors, and it is known that the sun radiates all colors of visible light, and in fact, radiates all frequencies of electromagnetic waves except for gamma rays, and this includes radio waves, microwaves, and infrared waves, Visible light, ultraviolet rays, and X-rays.
Who is the discoverer of the colors of sunlight?
The English physicist and mathematician Isaac Newton discovered that white light consists of 7 visible colors, after a series of experiments he conducted using sunlight and prisms in the sixties of the 16th century AD, where he explained that they include: red, orange, yellow, green, blue, and violet, And indigo, and white is produced when all the waves of the previous colors are seen together, and thus Newton’s experiments were able to provide the scientific basis for understanding color, and abolished the prevailing belief at the time, which included Aristotle’s opinion that color is the product of mixing white and black.
How to detect the colors of sunlight
Newton realized that the then-prevailing theory of color was wrong, although there were many proponents of it; Like the scientist Hooke, who was using a color scale ranging from bright red light to dull blue, Newton arrived at his theory after placing a prism near the window, and the sun’s rays passed through it, which resulted in a section consisting of all the colors of the spectrum on the wall that is 7 m away from him. To prove that the prism was not coloring the light, he broke the light back together in a beam of white light.
Isaac Newton's experiments are the real basis for the color circle that depends on the colors of the visible spectrum, as his theory states that the basic colors are red, blue, and yellow, although they are not completely correct, they are still visible in the color circle that was developed in the early The nineteenth century until the present color circle, which is similar to the circle of the Munsell color system, and the following are the groups of colors that make up the color circle:
- Primary colors include: red, yellow, and blue.
- Secondary colors: include: violet, orange, and green.
- Intermediate colors: are formed as a result of mixing primary colors with secondary colors, and include: yellow with orange, red with orange, red with violet, blue with violet, blue with green, and yellow with green.
The importance of the color circle lies in its ability to help designers and illustrators in all fields to create attractive palettes by applying the basic theory of the color circle, and understanding how to see color, such as palettes based on the complementary colors of the color circle, which refer to the opposite colors on the circle; Like red and green.
