  2. Color difference - Wikipedia

    en.wikipedia.org/wiki/Color_difference

    The CIE 1976 color difference formula is the first formula that related a measured color difference to a known set of CIELAB coordinates. This formula has been succeeded by the 1994 and 2000 formulas because the CIELAB space turned out to be not as perceptually uniform as intended, especially in the saturated regions.

  3. Template:Cell color - Wikipedia

    en.wikipedia.org/wiki/Template:Cell_color

    It interpolates the colour between given min and max values and colors (if not specified, these are assumed to be white for the min and black for the max). The font colour is turned black or white depending on the luminosity of the cell background. The background color is generated by the {{Value color}} template.

    Numbers is a spreadsheet application developed by Apple Inc. as part of the iWork productivity suite alongside Keynote and Pages. [2] Numbers is available for iOS and macOS High Sierra or newer. [3] Numbers 1.0 on Mac OS X was announced on August 7, 2007, making it the newest application in the iWork suite.

  5. MTT assay - Wikipedia

    [1] [2] NAD(P)H-dependent cellular oxidoreductase enzymes may, under defined conditions, reflect the number of viable cells present. These enzymes are capable of reducing the tetrazolium dye MTT, which is chemically 3-(4,5-di methyl thiazol-2-yl)-2,5-diphenyltetrazolium bromide, to its insoluble formazan, which has a purple color. Other closely ...

  6. LMS color space - Wikipedia

    en.wikipedia.org/wiki/LMS_color_space

    Normalized responsivity spectra of human cone cells, S, M, and L types (SMJ data based on Stiles and Burch [1] RGB color-matching, linear scale, weighted for equal energy) [2] LMS (long, medium, short), is a color space which represents the response of the three types of cones of the human eye , named for their responsivity (sensitivity) peaks ...

  7. Help:Advanced table formatting - Wikipedia

    en.wikipedia.org/wiki/Help:Advanced_table_formatting

    Solution: divide one of the tall cells so that the row gets one rowspan=1 cell (and don't mind the eventual loss of text-centering). Then kill the border between them. Don't forget to fill the cell with nothing ({}). This being the only solution that correctly preserves the cell height, matching that of the reference seven row table.

  8. CIE 1931 color space - Wikipedia

    en.wikipedia.org/wiki/CIE_1931_color_space

    When two or more colors are additively mixed, the x and y chromaticity coordinates of the resulting color (x mix,y mix) may be calculated from the chromaticities of the mixture components (x 1,y 1; x 2,y 2; …; x n,y n) and their corresponding luminances (L 1, L 2, …, L n) with the following formulas: [16]

  9. Color space - Wikipedia

    en.wikipedia.org/wiki/Color_space

    A "color model" is an abstract mathematical model describing the way colors can be represented as tuples of numbers (e.g. triples in RGB or quadruples in CMYK); however, a color model with no associated mapping function to an absolute color space is a more or less arbitrary color system with no connection to any globally understood system of ...
