The perception of colour is a highly subjective experience.
The colour of nearby objects can influence colour perception.
The environment in which colours are observed and the type of object can influence colour perception.
The physical properties of light, including wavelength and intensity, can affect how colours are perceived.
An observer’s physical and mental state can affect their perception of colour. Health, medications, mood, emotions, or fatigue can all affect an observer’s eyes, vision, and perception.
Different observers may perceive colours differently based on their life experiences, linguistic backgrounds, and educational, social, and cultural factors.
The term “observer” has distinct meanings in various scientific fields, such as special relativity, general relativity, quantum mechanics, thermodynamics, and information theory.
