Light refers to the electromagnetic radiation that is visible to the human eye, while color is the perception of different wavelengths of light by the human eye. In other words, light is the physical phenomenon that allows us to see, while color is the way our brain interprets different wavelengths of light. Light can exist without color, but color cannot exist without light.

Light and color are closely related concepts but represent distinct physical phenomena.
Light:
- Definition: Light is a form of electromagnetic radiation that can be perceived by the human eye.
- Properties: Light has a wavelength, frequency, and amplitude. The wavelength determines the color of light, the frequency determines its energy, and the amplitude determines its intensity (brightness).
- Source: Light can be emitted by various sources, such as the sun, stars, and artificial lighting.
Color:
- Definition: Color is the perceptual experience of the human eye when exposed to light of different wavelengths.
- Properties: Color is described by three main attributes: hue, saturation, and value or brightness. Hue is the qualitative aspect of color (e.g., red, blue, green), saturation is the intensity or purity of the color, and value is the lightness or darkness of the color.
- Perception: Color perception is subjective and varies across individuals and species due to differences in the structure and sensitivity of the eye's photoreceptor cells (cone cells).
Key Differences:
- Objective vs. Subjective: Light is an objective physical phenomenon, while color is a subjective perceptual experience.
- Wavelength vs. Perception: Light is characterized by its wavelength, while color is determined by the way the eye interprets light of different wavelengths.
- Spectrum: Light encompasses all electromagnetic radiation, including visible light, ultraviolet light, and infrared light. Color, on the other hand, refers specifically to the visible spectrum of light.
In summary, light is the physical stimulus that enables us to perceive color. Different wavelengths of light produce different colors, which are then perceived and interpreted by the human eye.
