A color circle is traditional in the field of art. Sir Isaac Newton developed the first circular diagram of colors in 1666. Since then scientists and artists have studied and designed numerous variations of this concept. Differences of opinion about the validity of one format over another continue to provoke debate. In reality, any color circle or color wheel which presents a logically arranged sequence of pure hues has merit.
In traditional color theory, RED . BLUE . YELLOW are the 3 pigment colors that can not be mixed or formed by any combination of other colors. All other colors are derived from these 3 hues.
Basic techniques for combining colors:
1. Complementary colors

Some contrasting colors: red-green . blue-orange . red-purple
Complementary colors are tricky to use in large doses, but work well when you want something to stand
out. They are also really bad for text.
2. Analogous colors
Analogous colors are any three colors which are side by side on a 12 part color wheel:
yellow-green . yellow-orange
Make sure you have enough contrast when choosing an analogous color scheme.
Choose one color to dominate, a second to support.
The third color is used along with black . white . gray as an accent.
3. Triads color
Choose one color to dominate, a second to support.
The third color is used along with black . white . gray as an accent.
3. Triads color
By placing an equilateral triangle on the color wheel, you can create color schemes that have a lot of life to them.
The most basic color triad: red . yellow . blue
Others are: green . purple . orange
4. Split complementary
The split-complementary color scheme is a variation of the complementary color scheme. In addition to the base color, it uses the two colors adjacent to its complement.
This color scheme has the same strong visual contrast as the complementary color scheme, but has less tension. It is often a good choice for beginners, because of the difficulty to be messed up, such:
pink . orange . green
pink . orange . green
But when looking for the best color schemes, the first place I start is nature. The color schemes found are typically harmonious to our eyes. This can be the case even if the colors don't "go together" according to color theory. Praise Allah for creating a beautiful nature colors.
