To understand the concept of pure colors, we need to delve into the world of color theory. Pure colors, also known as spectral colors, are the hues that can be found on the visible spectrum of light. These colors are not mixed with white, black, or gray, making them vibrant and distinct.
What Are the 7 Pure Colors?
The seven pure colors are red, orange, yellow, green, cyan, blue, and violet. These colors represent the visible spectrum of light and are often associated with the rainbow. Each color has a unique wavelength and can be seen in natural phenomena like rainbows and prisms.
Understanding Pure Colors and Their Characteristics
What Defines a Pure Color?
A pure color is one that is not mixed with any other hue, tint, or shade. These colors are found in the spectrum of light and are considered the building blocks of all other colors. The purity of a color affects its vibrancy and intensity.
How Do Pure Colors Appear in Nature?
- Rainbows: Formed when sunlight is refracted, reflected, and dispersed by water droplets in the atmosphere, displaying the seven pure colors.
- Prisms: When light passes through a prism, it is split into its spectral components, revealing pure colors.
- Natural Light: Daylight is a mixture of all pure colors, which is why it appears white.
The Science Behind Pure Colors
Why Do We See Seven Pure Colors?
The human eye perceives color through light receptors called cones. There are three types of cones, each sensitive to different wavelengths corresponding to the primary colors: red, green, and blue. The combination of these receptors allows us to perceive the full spectrum of colors.
What Are the Wavelengths of Pure Colors?
| Color | Wavelength Range (nm) |
|---|---|
| Red | 620-750 |
| Orange | 590-620 |
| Yellow | 570-590 |
| Green | 495-570 |
| Cyan | 485-495 |
| Blue | 450-485 |
| Violet | 380-450 |
