  2. Munsell color system - Wikipedia

    en.wikipedia.org/wiki/Munsell_color_system

    The Munsell color system, showing: a circle of hues at value 5 chroma 6; the neutral values from 0 to 10; and the chromas of purple-blue (5PB) at value 5. In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), value ( lightness ), and chroma (color intensity).

  3. Shades of purple - Wikipedia

    en.wikipedia.org/wiki/Shades_of_purple

    This color is defined as purple in the Munsell color system (Munsell 5P). The Munsell color system is a color space that specifies colors based on three color dimensions: hue , value ( lightness ), and chroma (color purity), spaced uniformly in three dimensions in the elongated oval at an angle shaped Munsell color solid according to the ...

  4. ColorChecker - Wikipedia

    en.wikipedia.org/wiki/ColorChecker

    The ColorChecker Color Rendition Chart (often referred to by its original name, the Macbeth ColorChecker [1] or simply Macbeth chart [2]) is a color calibration target consisting of a cardboard-framed arrangement of 24 squares of painted samples. The ColorChecker was introduced in a 1976 paper by McCamy, Marcus, and Davidson in the Journal of ...

  5. Lightness - Wikipedia

    en.wikipedia.org/wiki/Lightness

    In colorimetry and color appearance models, lightness is a prediction of how an illuminated color will appear to a standard observer. While luminance is a linear measurement of light, lightness is a linear prediction of the human perception of that light. This distinction is meaningful because human vision's lightness perception is non-linear ...

  6. Farnsworth–Munsell 100 hue test - Wikipedia

    en.wikipedia.org/wiki/Farnsworth–Munsell_100...

    The Farnsworth–Munsell 100 Hue Color Vision test is a color vision test often used to test for color blindness.The system was developed by Dean Farnsworth in the 1940s and it tests the ability to isolate and arrange minute differences in various color targets with constant value and chroma that cover all the visual hues described by the Munsell color system.

  7. RAL colour standard - Wikipedia

    en.wikipedia.org/wiki/RAL_colour_standard

    RAL colour standard. RAL is a colour management system used in Europe that is created and administered by the German RAL gGmbH [ de] [1] (RAL non-profit LLC), which is a subsidiary of the German RAL Institute [ de]. In colloquial speech, RAL refers to the RAL Classic system, mainly used for varnish and powder coating, but now plastics as well.

    The color defined as yellow in the Munsell color system (Munsell 5Y) is shown at apex of color wheel. The Munsell color system is a color space that specifies colors based on three color dimensions: hue, value , and chroma (color purity), spaced uniformly in three dimensions in the elongated oval at an angle shaped Munsell color solid according ...

  9. Line of purples - Wikipedia

    en.wikipedia.org/wiki/Line_of_purples

    In color theory, the line of purples or purple boundary is the locus on the edge of the chromaticity diagram formed between extreme spectral red and violet. Except for these endpoints of the line, colors on the line are non-spectral (no monochromatic light source can generate them). Rather, every color on the line is a unique mixture in a ratio ...
