This article describes basic properties of color, what relationships are between them and differences between what you see and what you actually get using your inkjet cartridges.
Most of you will have come across these three; Hue, Saturation and Brightness; if you have ever messed around with color settings of your images.
Hue: For example; blue, green and violet are all hues. They are colors. The dictionary definition of 'Hue' is; "the attributes of colors that permits them to be classed as red, yellow, green, blue or an intermediate between any adjacent pair of these colors."
Saturation: This refers to how vivid color is. The higher amount of gray relative to amount of hue, less vivid it will be.
Brightness: Relates to relative darkness or lightness of color.
In 1905 American artist A. Munsell published a color measurement system, naming three parameters, Hue, Value and Chroma (Hue, Saturation and Brightness as above). This three dimensional relationship resulted in color identification in this format, for example; 7.5YR 7/12. Here we have a yellow-red hue tending with a value of 7 and a chroma of 12. There are 40 pages in book covering all colors in complete Munsell system.
Monitor and printer color production
Printer: Printer colors are produced from inkjet cartridges emitting minute patterns of ink dots placed on paper. All colors that you see come from just four colors; cyan (C), magenta (M), yellow (Y) and black (K).
As an aside, a mixture of cyan, magenta and yellow should produce black, but in reality a touch of black is needed to get it.
Monitor A phosphor is a substance that emits light when subjected to radiation. Color phosphors are illuminated with electrons in your monitor and hence images are produced. There are three colored phosphors in each pixel on screen; red (R), green (G) and blue (B).
