Colorants appear certain colors based on the wavelength of light they reflect. Color can be measured and described using spectrophotometers. But, the trained human eye can achieve good color matches just as effectively.
Terms used to describe color include:
- Hue – This is the actual color, e.g. red, blue or yellow
- Value or Luminosity – The higher the value or luminosity, the more white that is in the color
- Chroma or saturation – The intensity of the hue relative to the value or luminosity of the color
Colors are measured using a variety of systems, which can include:
- Pantone color charts
- The Munsell color system
- The British Colour Council Dictionary of Color Standards
