Color is the visual perception resulting from the way light interacts with objects and is reflected back to our eyes. It is a property of an object that is determined by the wavelengths of light that it reflects, absorbs, or emits. Colors are typically described in terms of their hue (the specific shade or tint), saturation (the intensity or purity of the color), and brightness (the lightness or darkness of the color).

Colour, also known as hue, is a perception of light of different wavelengths by the human eye and brain. It is a visual experience that evokes a wide range of emotions and associations.
Perception of Colour:
- When light hits the retina of the eye, it is detected by photoreceptors called cones.
- Cones contain pigments that are sensitive to different wavelengths of light.
- There are three types of cones:
- Red cones: Sensitive to longer wavelengths (620-750 nm)
- Green cones: Sensitive to middle wavelengths (495-570 nm)
- Blue cones: Sensitive to shorter wavelengths (420-440 nm)
- The combination of signals from these three types of cones creates our perception of colour.
Colour Spectrum:
The visible spectrum of light consists of a range of wavelengths, from violet (shortest) to red (longest). When light of different wavelengths passes through a prism or is dispersed by nature (e.g., a rainbow), it separates into its constituent colours.
Colour Theory:
Colour theory describes the relationships and harmonies between different colours. The two main colour theories are:
- Additive Colour Model: Used in monitors, screens, and projectors. Combines red, green, and blue (RGB) light to create a wide range of colours.
- Subtractive Colour Model: Used in paints and dyes. Combines cyan, magenta, and yellow (CMY) to create a range of colours.
Psychological and Emotional Effects of Colour:
Colours can evoke strong emotions and associations:
- Red: Energy, passion, danger
- Green: Nature, growth, stability
- Blue: Tranquility, harmony, sadness
- Yellow: Happiness, optimism, stimulation
- Purple: Royalty, mystery, spirituality
Uses of Colour:
Colour is used in various applications, including:
- Art and design: Creating visual interest and impact
- Marketing and advertising: Influencing consumer behaviour
- Interior design: Creating moods and atmospheres
- Science and medicine: Diagnostic tests, colour therapy
- Psychology: Understanding personality traits and emotions
