Hue is one of the three main properties of colour, alongside saturation and brightness and is described using names such as red, yellow, green or blue.
- Hue refers to the colour of an object or light source, and is determined by the dominant wavelength of light it emits or reflects.
- Hue is often used to describe colours in terms of their position on the colour wheel. Colour wheels are circular diagrams that arrange colours according to their hue.
- The most commonly used colour wheel is the RGB colour wheel, which includes primary colours (hues) of red, green and blue, as well as secondary and tertiary colours.
- Hues can be warm or cool, depending on their position on the colour wheel. Warm hues are those that include red, orange and yellow, while cool hues include blue, green and purple.
- The perceived brightness and saturation of a hue can be affected by its surrounding colours, as well as by lighting conditions.
- The perception of hue is also influenced by cultural and personal associations, as well as context and other environmental factors.
