Color And Contrast
Contrast can be defined as the difference in visual properties that makes an object (or its representation in an image) distinguishable from other objects and the background.
Contrast is the perceived difference in colors that are in close proximity to each other. Using contrast effectively not only differentiates your design from others, it’s the essential ingredient that makes content accessible to every viewer.
The Pure Color (Hue) Contrast
This results when pure colors are used in random combinations. White and black can further enhance the vivid effect.
The Light-Dark Contrast
This is based on the use of different brightnesses and tone values of the colors. All colors can be lightened with white, and darkened with black.
The Cold-Warm Contrast
It´s greatest effect is achieved with the colors orange-red and blue-green. All other colours appear cold or warm depending on their contrast with warmer or colder hues.
The Complementary Contrast
In the color circle the complementary colors occupy opposite positions. When they are mixed, the result is a neutral grey-black. When adjacent, complementary colors mutually intensify their luminosity to a maximum; when mixed, they extinguish each other to produce grey-black.
The Simultaneous Contrast
Its effect is derived from the law of complementary colours, according to which each pure colour physiologically demands its opposite colour – its complement. If this colour is absent, the eye will produce it simultaneously. Strong green makes neutral grey next to it appear reddish-grey, whereas the effect of strong red on the same grey is a greenish-grey appearance.
The Contrast of Quality (Color Saturation)
This is the contrast between luminous and dull colors. Colors can be subdued by the addition of black, white, grey, or complementary colors.
The Contrast of Quantity
This is based on the opposition of colored areas of different sizes.
