What Makes the Color Yellow?
The Physics of Color in the Visible Spectrum
When we talk about the color yellow, we are referring to a specific wavelength of light in the visible spectrum. To understand the physics behind the color yellow, we must first understand light itself. Light is a form of energy that can be broken down into multiple wavelengths. Visible light, which is the light that humans can see, is made up of many wavelengths that range from red to violet.
The Color Yellow in the Visible Spectrum
In the visible spectrum, yellow is located between green and orange. The wavelength of yellow light is around 570 nanometers, which is slightly longer than green and slightly shorter than orange. When light of this wavelength enters the eye, the human brain interprets it as the color yellow.
The Chemistry of Yellow Pigments
The color yellow can also be created with pigments, which are colored chemicals that absorb particular wavelengths of light. Examples of yellow pigments include cadmium yellow, chrome yellow, and Indian yellow. Each of these pigments absorb certain wavelengths of light and reflect others, creating the perception of the color yellow.
The Psychology of the Color Yellow
In addition to its physical properties, the color yellow has psychological associations. In some cultures, yellow is associated with happiness and joy. In others, it is associated with caution and cowardice. The psychological associations of the color yellow can vary depending on the culture and context.
Conclusion
The color yellow is a specific wavelength of light in the visible spectrum. It can also be created using pigments, which are colored chemicals that absorb and reflect certain wavelengths of light. The psychological associations of the color yellow can vary from culture to culture.
