Variants of TIFF can be used within document imaging and content/document management systems using CCITT Group IV 2D compression which supports black-and-white (bitonal, monochrome) images, among other compression technologies that support color. When storage capacity and network bandwidth was a greater issue than commonly seen in today's ...

In some systems, as Hercules and CGA graphic cards for the IBM PC, a bit value of 1 represents white pixels (light on) and a value of 0 the black ones (light off); others, like the Atari ST and Apple Macintosh with monochrome monitors, a bit value of 0 means a white pixel (no ink) and a value of 1 means a black pixel (dot of ink), which it ...
This is achieved by encoding RGB image data into a composite black and white image, with separated color difference data . For example with Y ′ C b C r {\displaystyle Y'C_{b}C_{r}} , gamma encoded R ′ G ′ B ′ {\displaystyle R'G'B'} components are weighted and then summed together to create the luma Y ′ {\displaystyle Y'} component.
Color images can be converted to black and white on the computer using several methods, including desaturating the existing color RGB image so that no color remains visible (which still allows color channels to be manipulated to alter tones such as darkening a blue sky), or by converting the image to a greyscale version (which eliminates the ...
To convert a color from a colorspace based on a typical gamma-compressed (nonlinear) RGB color model to a grayscale representation of its luminance, the gamma compression function must first be removed via gamma expansion (linearization) to transform the image to a linear RGB colorspace, so that the appropriate weighted sum can be applied to ...
To use a colour in a template or table you can use the hex triplet (e.g. #CD7F32 is bronze) or HTML color name (e.g. red).. Editors are encouraged to make use of tools, such as Color Brewer 2 to create Brewer palettes, listed at MOS:COLOR for color scheme selection used in graphical charts, maps, tables, and webpages with accessibility in mind for color-blind and visually impaired users.
The type of color profile that is typically used is called an ICC profile. A cross-platform view of color management is the use of an ICC-compatible color management system. The International Color Consortium (ICC) is an industry consortium that has defined: an open standard for a Color Matching Module (CMM) at the OS level; color profiles for:
