Why your brain sees color as a subjective human experience
In short: Color is more than just light; it is a complex interplay of physics and psychology. This talk explores how we quantify a perception that is inherently versatile and variable, from consumer influence to biological warnings.
Andrew Hanson, a scientist with the UK’s National Measurement Institute, explores the challenges of assigning numerical values to human perception. While color is rooted in the physics of light, it functions as a powerful tool for communication, influencing consumer behavior, providing comfort, and issuing warnings.
Drawing on 25 years of experience, Hanson demonstrates how color measurement applies to diverse fields, including the calibration of visual display units and even measuring the shininess of cats. The talk uses optical illusions and demonstrations to reveal how much of our visual experience is shaped by the mind rather than just the eyes.
