2. Fundamental Principles of Light and Color

a. The Physics of Light: Wavelength, Intensity, and the Electromagnetic Spectrum

Light is an electromagnetic wave characterized by its wavelength and intensity. The visible spectrum ranges from approximately 380 nm (violet) to 740 nm (red). Each wavelength corresponds to a specific color perceived by the human eye. The intensity of light influences brightness, while variations in wavelength produce the rich tapestry of colors we observe. For example, the vibrant blue of a clear sky results from Rayleigh scattering of shorter wavelengths, while the warm oranges of a sunset are due to longer wavelengths dominating as the sun’s rays pass through the atmosphere.

b. Human Eye Anatomy and How It Processes Different Wavelengths

The human eye contains photoreceptor cells called rods and cones. Cones are responsible for color vision and are sensitive to different wavelengths: short (blue), medium (green), and long (red). The brain interprets signals from these cones to produce the perception of a full spectrum of colors. The eye’s design allows us to detect subtle differences in hue and brightness, enabling tasks from reading to appreciating art.

c. The Psychology of Color Perception: Emotional and Cognitive Responses

Colors evoke emotional reactions and influence cognition. Red can stimulate excitement or urgency, blue often induces calmness, and yellow may evoke happiness. These responses are rooted in both biological hardwiring and cultural associations. For instance, studies have shown that warmer colors tend to increase arousal, impacting decision-making and mood, which is crucial in marketing and interior design.

3. The Interaction Between Light, Color, and Human Brain
