Colour Properties Swee Shi Ning Zoey & Shawn Ong What is colour? ● visual byproduct of the spectrum of light as it is either transmitted through a transparent medium, or as it is absorbed and reflected off a surface ● light wavelengths that the human eye receives and processes from a reflected source Colour Wheel ● Initial Inventor: Sir Issac Newton ● an abstract illustrative organization of color hues around a circle ● shows the relationships between primary colors, secondary colors, tertiary colors Overview 1. Hue 2. Tint 3. Shade 4. Tone 5. Saturation 6. Value - Lightness/Darkness 7. Chroma 8. Intensity /Luminosity 9. Grayscale 1. Hue ● Hue defines pure color ● 3 Main components: ○ Primary ○ Secondary ( Mix of 2 primary hues) ○ Tertiary ( Created by mixing adjacent primary and secondary hues) The science behind hues ● Hue describes the dominant wavelength of the color. ● Each hue represents a particular wavelength of visible light ● Visible light: 400 to 700 nm 2. Tint ● Mixing result of a pure hue + white ● Lighter than the original colour ● When used as a dimension of a color space, tint can be the amount of white added to a pure hue. 3. Shade ● Mixing result of a pure hue + black ● Darker than the original colour ● When used as a dimension of a color space, shade can be the amount of black added to a pure hue. 4. Tone ● Created when both black and white or grey is added to a hue ● Tones can be darker or lighter than the original hue Overview (Hue, Tint, Shade, Tone) 5. Saturation ● A color term commonly used by (digital / analog) imaging experts ● Refers to the intensity of color in an image ● Technical terms: expression of the bandwidth of light from a source Albert Henry Munsell ● Inventor of the Munsell color system back in late 1800s ● American Painter ● Teacher of Art ● Dimension of Hue, value, and chroma 6. Value - Lightness/Darkness Value is the lightness or darkness of a color. 7. Chroma ● The term chroma was invented by Munsell(1905) ● The quality of color’s purity, intensity or saturation. Low Chroma & High Chroma Overview of Saturation Value & Chroma A certain color can be defined by hue (0° - 360°), saturation (0% - 100%) and lightness (0% - 100%). 8. Intensity / Luminosity Luminosity can influence colors 9. Grayscale ● A grayscale is a series of neutral colors ● A grayscale color can be determined by a value of a one-dimensional color space. ● Black surface (eg. Monitor) relative intensity of white (light) applied to the medium.
