Every colour is seen in relationship to another colour. When you see two or more colours together they have a profound effect on one another. The study of colour interaction helps us understand and predict how a colour will be influenced by its surroundings.
The different types of color contrast are the following:
1. Contrast of hue
2. Light-dark contrasts
3. Cold- warm contrasts
4. Complementary contrast
5. Simultaneous contrast
6. Contrast of saturation
7. Contrast of extension
• Colour Interaction:
Contrast of Hue:
Contrast of Hue occurs when a hue or color is separated and outlined by black or white lines. White lines weaken the 'strength' and appearance of the color and the colors around the white lines would seem darker. Similarly, a black line strengthens the appearance of the color and the colour around the black lines would seem lighter.
The strongest expression of contrast.
Colors of greatest luminosity.
Colors of greatest luminosity with tints and shades.
Light-Dark Contrasts:
Light dark contrast is contrast between light values and dark values. The strongest expressions of light and dark are the colors white and black.
Light color of equal brilliance.
Light & dark composition in white, gray and blue.
Colors of equal darkness.
Cold - Warm Contrasts:
Cold-warm contrast refers to the contrast between cool and warm colors. Cools colors consist of blue, green and purple. Warm colors consist of red, orange and yellow. As seen in the colour wheel yellow is the lightest and violet the darkest hue; hence these two hues have the strongest light-dark contrast. Hues can be either cold or warm according to warmer or colder tones they are contrasted with.
Warm – cool contrast.
Blue as a warm.
Blue as a cool.
Cold warm modulation in red.
Cold warm contrast.
Complementary Contrast:
Complimentary Contrast refers to the contrast between complimentary (opposite) colors. Complimentary colors are those that are directly opposite to each other on the color wheel. Each complementary pair has its own peculiarities. Red-orange/blue-green is a complementary pair as well as the extreme of cold warm contrast. Red and green are complementary, and the two saturated colors have the same brilliance.
Simultaneous Contrast:
It is the contrast between a color and another color that is to the right of left of its compliment. Each of seven pure color squares contains a small neutral gray square, matching the background color in brilliance. Each gray square seems to be tinged with the complementary of the background. The simultaneous effect becomes more intense, the longer the principal color of a square is viewed.
Contrast of Saturation:
It is the contrast between pure intense colors and dull diluted or grayed colors. Dull colors would appear to be duller when it is placed next to pure intense colors, and pure intense colors would appear move vivid when it is next to a dull color.
On a checkered pattern of 3 squares, luminous yellow, orange, red, or blue is placed in the center The four corners are neutral gray in the same brilliance as the pure color. Graded admixture of gray with the pure color produces intermediate shades of low saturation.
Contrast of Extension:
It refers to the contrast between the proportions of one area of color to another. Contrast of extension involves the relative areas of two or more color patches; it is the contrast between much and little, or great and small.
Yellow squares of equal size look bigger on white than on black.
Red squares of equal size look smaller than on black.

Colour Harmony:
Colour harmony is the synchronization, balance or the pleasingness of a group of colour.
Acromatic Colour Scheme:
The “hueless” colors black, gray, and white, - the whole range of gray levels between black and white.
Complementary Color Scheme:
Colours that are directly opposite to each other in a colour wheel and appear opposite in character are called complementary colours. They create a vibrant effect.
Analogous Color Scheme:
Analogous color schemes use colors that are next to each other on the color wheel. They usually match well and create harmonious effect.
Triadic Color Scheme:
A triadic color scheme uses colors that are evenly spaced around the color wheel.
Split-Complementary Color Scheme:
The split-complementary color scheme is a variation of the complementary color scheme. A colour and the two colours adjacent to it’s direct complement. It has high contrast but less contrast than complimentary colours.
Tetradic Color Scheme:
The rectangle or tetradic color scheme uses four colors arranged into two complementary pairs. It offers plenty of possibilities for variation.
Temperature:
The temperature of a colour is its relative warmth or coolness. Cool colours contain blue or green: blues, greens, violets, and steps between them. Warm colours are reds, oranges, yellow, and steps between them.
