caption_attribution_description: English: Pier Andrea Saccardo's 1894 chromotaxy scale, plates I and II from Chromotaxia, seu nomenclator colorum... ad usum botanicorum et zoologorum (in English, French, German, Italian, and Latin) – digital facsimile from the Linda Hall Library
context_page_description: A color chart or color reference card is a flat, physical object that has many different color samples present. They can be available as a single-page chart, or in the form of swatchbooks or color-matching fans.
  Typically there are two different types of color charts:
  Color reference charts are intended for color comparisons and measurements. Typical tasks for such charts are checking the color reproduction of an imaging system, aiding in color management or visually determining the hue of color. Examples are the IT8 and ColorChecker charts.
  Color selection charts present a palette of available colors to aid the selection of spot colors, process colors, paints, pens, crayons, and so on – usually the colors are from a manufacturers product range. Examples are the Pantone and RAL systems.
context_section_description: Pier Andrea Saccardo proposed this "chromotaxy scale" in 1894, to standardize the naming of colors of plant specimens.
  Color charts can take custom forms, as for example the calibration target used by the Curiosity rover for its Mars Hand Lens Imager (MAHLI).
