About the diagram
Some key terms
The trichromatic colour model is a theory of colour that establishes terms, rules and methods to enable human colour vision to be dealt with in both systematic and practical ways.
Visible light is the range of wavelengths of electromagnetic radiation perceived as colour by human observers.
- Visible light is a form of electromagnetic radiation.
- Other forms of electromagnetic radiation include radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays.
- Visible light is perceived by a human observer as all the spectral colours between red and violet plus all other colours that result from combining wavelengths together in different proportions.
- A spectral colour is produced by a single wavelength of light.
- The complete range of colours that can be perceived by a human observer is called the visible spectrum.
- The range of wavelengths that produce visible light is a very small part of the electromagnetic spectrum.
Colour vision is the human ability to distinguish between objects based on the wavelengths of the light they emit, reflect or transmit. The human eye and brain together translate light into colour.
- Colour is not a property of electromagnetic radiation, but a feature of visual perception.
- The human eye, and so human perception, is tuned to the visible spectrum and so to spectral colours between red and violet.
- Light, however, is rarely of a single wavelength, so an observer will usually be exposed to a range of different wavelengths of light or a mixture of wavelengths from different areas of the spectrum.
- A person’s perception of colour is a subjective process whereby the brain responds to the stimuli that are produced when incoming light reacts with several types of photosensitive cone cells in the eye. In essence, different people see the same illuminated object or light source in different ways.
- Colours can be organised and quantified and colour theory helps to make sense of its appearance in different situations.
Colour is not a property of electromagnetic radiation, but a feature of visual perception by an observer.
- The human eye and so human visual perception are tuned to the visible spectrum and so to spectral colours between red and violet.
- There are no properties of electromagnetic radiation that distinguish visible light from other parts of the electromagnetic spectrum.
- Objects appear to be different colours to an observer depending on the wavelengths, frequencies and amplitude of visible light at the moment it strikes the retina at the back of the eye.
