Channels Separation
Answers to Questions (FAQ)
What are channels of an image? (Definition)
Colors are usually represented with several components, channels that can describe them. In computer, the display (via a screen) is achieved by 3 color components, the red, green and blue channels (RVG or RGB). In print (on paper), printing is done in four color components: the cyan, magenta, yellow and black channels.
On the web in general, the current representation is an encoding that uses additive colors with 3 components: red (R), green (G) and blue (B) (called RGB channels).
In all cases, from a color image, it is possible to separate each of the channels.
Example: Blue Channel 
What are CMYK channels?
In printing, the current representation is an encoding that uses subtractive colors with 4 layers: cyan, magenta, yellow and black (key) (see CMYK channels separation).
What are TSL channels?
In science and photography, prefer using a vector space of color with 3 parameters: hue, saturation and brightness (value), hence the name HSV channels.
