Exploring the intricacies of colour perception, this content delves into the physics of light, the visible spectrum, and how human biology interprets these signals. It covers the wavelength-dependent nature of colour, the principles of additive colour mixing, and the impact of light absorption on the appearance of objects. Additionally, it discusses the biological mechanisms of human colour vision and the variables that influence colour perception in natural and artificial environments.

The visible spectrum is the range of electromagnetic wavelengths that can be detected by the human eye, with each colour corresponding to a unique wavelength
Principles of Additive Colour Mixing
Additive colour mixing involves combining different colours of light to create new colours, rather than a blend of the original hues
The colours we perceive in objects are due to the selective absorption and reflection of light wavelengths, with an object's colour determined by the wavelengths it does not absorb
The human visual system relies on cone cells, which are sensitive to different segments of the visible spectrum, to interpret and distinguish a wide range of colours
Material Composition and Illumination Conditions
The material composition of an object and the colour of the incident light can influence its perceived colour, along with the observer's visual system
Effects of Sunlight and Atmospheric Conditions
Sunlight and atmospheric conditions, such as scattering and artificial lighting, can significantly alter the appearance of colours outdoors
