Color Space Color Model
A color space is an arbitrary agreed upon way to define color.
Hexadecimal color are used on web pages to specify colors. Hexadecimal color codes always begin with a hash (#). Different combinations can produce different color. Such as color blue, the color code is #0000FF, which is '0'red, '0'green and '255' blue. These color codes can be used to change the color of background, tables and text.
RGB Color Model
RGB Color Model is one of color standards in industrial community, and is one of most widely used color systems at present. It is an additive primary model in which red, green and blue light is added together in different ways to reproduce a broad array of colors. RGB is an initialism for redCgreenCblue.
CMYK Color Model
The CMYK color model is a subtractive color model, is also called process color or four colors. It is used for Color printing which typically uses ink of four colors: cyan, magenta, yellow, and key (black).In order to save money on ink, and to produce deeper black tones, unsaturated and dark colors are produced by using black ink instead of the combination of cyan, magenta and yellow.
HSL and HSV Color Model
HSL and HSV are the two most common cylindrical-coordinate on behalf of points in an RGB color model, which rearrange the geometry of RGB trying to be more intuitive. HSL (also called HLS) stands for hue, saturation, and lightness, which is founded by Alvy Ray Smith in 1978. HSV (also called HSB, B for brightness) stands for hue, saturation, and value. HSI is a third model, common in computer vision applications, which stands for hue, saturation, and intensity.
XYZ color space
XYZ color space is also called CIE RGB color space, which is created by the International Commission on Illumination (CIE) in 1931.The CIE RGB color space is one of many RGB color spaces, distinguished by a particular set of monochromatic (single-wavelength) primary colors.
CIE xyY Color Space
The derived color space specified by x, y, and Y is known as the CIE xyY color space. Because the top curved edge represents pure colors and all of the colors which can be created by mixing two colors will be found along a straight line between those two colors, it is diffusely used to specify colors in practice.
CIE-LAB Color Space
A Lab color space (also called CIELAB, whose coordinates are actually L*, a*, and b*) is a color-opponent space with dimension L for lightness and a and b for the color-opponent dimensions, based on nonlinearly compressed CIE XYZ color space coordinates. The Lab color space includes all perceivable colors, it means that its gamut exceeds those of the RGB and CMYK color models. It is popularly used in color manipulation software. Lab stands for Luminance, red to green, and blue to yellow.
CIE-Lch Color Space
CIE-Lch, can be thought of as the cylindrical version of CIELUV, and it uses color space same as Lab color sapce. LCH stands for Luminance,Chromaticity, and Hue Angle.
