RGBA stands for red green blue alpha. While it is sometimes described as a color space, it is actually a three-channel RGB color model supplemented with a fourth alpha channel. Alpha indicates how opaque each pixel is and allows an image to be combined over others using alpha compositing, with transparent areas and anti-aliasing of the edges of ...
A diagram demonstrating additive color with RGB. The RGB color model is an additive color model [1] in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
In computing, on the X Window System, X11 color names are represented in a simple text file, which maps certain strings to RGB color values. It was traditionally shipped with every X11 installation, hence the name, and is usually located in <X11root> /lib/X11/rgb.txt. The web colors list is descended from it but differs for certain color names.

Channel (digital image) Color digital images are made of pixels, and pixels are made of combinations of primary colors represented by a series of code. A channel in this context is the grayscale image of the same size as a color image, [citation needed] made of just one of these primary colors. For instance, an image from a standard digital ...
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation CMYK refers to the four ink plates used: c yan, m agenta, y ellow, and k ey (black).
Demosaicing (or de-mosaicing, demosaicking ), also known as color reconstruction, is a digital image processing algorithm used to reconstruct a full color image from the incomplete color samples output from an image sensor overlaid with a color filter array (CFA) such as a Bayer filter. It is also known as CFA interpolation or debayering .
Blend modes. A sketch colored digitally with use of several different blend modes in order to preserve the pencil lines and paper texture below the color layers. Blend modes (alternatively blending modes [1] or mixing modes [2]) in digital image editing and computer graphics are used to determine how two layers are blended with each other.
