Understanding the uses of color is crucial to composition in fine arts and design.
There are many systems for classifying
hue (color), developed so that researchers can measure and define color qualities.
Our
perceptions are affected by the various physical phenomena and psychological effects too.
RBG color model:
Light Primaries - red, blue, green.
This definition is active when colored light is mixed, as on your computer or TV screen.Its effects are less familiar than pigment mixture to most people.
If all three primaries are mixed, the theoretical result is white light. Therefore light mixture is sometimes referred to as
additive mixture.
CMYK color model:
Printers primaries or the subtractive primaries- magenta, cyan (turquoise), yellow: this represents the basis for color printing.
In theory, mixing equal amounts of all three pigments should produce gray (black)but in practice they tend to produce muddy brown colors. For this reason, a fourth pigment, black (the key), is often used in addition to cyan, magenta, and yellow.
RYB color model:
Painters primaries - red, blue, yellow - are also
substractive primaries.
Though painters have long used more than three primary colors in their palettes, red, yellow, blue, and green are still widely considered the four psychological primary colors in combination with black and white.
This traditional color model is primary used in painting and art education. It is based on 19th century theories where triads are formed by 3 equidistant colors on the traditional color wheel.
In the upcoming articles this is what I shall talk about.
