What is the colour wheel use for?

Answer 1

A color wheel is disk-shaped and divided equally into 12 sections, each displaying a different color according to its "pigment" values. All colors arise from the three primary colors: red, blue and yellow. These colors are primary because you cannot make them by mixing other colors together. They are represented on the color wheel at equidistant positions, forming a triangle. Mixing equal values of any two primary colors together creates the secondary colors of violet, orange and green. Since violet is a combination of equal amounts of blue and red, it lies halfway between those two colors on the color wheel. Orange lies halfway between red and yellow, and green between yellow and blue. The secondary colors form another triangle. To fill the last 6 spaces on the color wheel, the tertiary colors are represented. Adding equal amounts of one primary and one secondary color, or the colors to either side on the wheel, results in the tertiary colors between. Flanked by red and orange you will see red-orange, between orange and yellow, yellow-orange, followed by yellow-green, blue-green, blue-violet, and red-violet. A color wheel is extremely handy when putting together a color scheme, or series of colors that will compliment each other to create an overall pleasing affect. Following are some basic color schemes: Monochrome: A single color is used, varied in saturation and lightness for several different contrasting shades. Many "skins" for software use a monochromatic color scheme. One problem with this color scheme is that it is difficult to make anything stand out, and the lack of contrast can get monotonous. Analogous : Here you use the color wheel to pick two colors that are side-by-side. One becomes the dominant color and the other is used to accent. The overall effect is much like the monochrome scheme but offers more hues. However, it still lacks contrast. Complimentary : Using the color wheel, complimentary colors are found opposite each other. This creates high contrast. Again one of the two colors should be dominant. This color scheme is harder to balance in a pleasing way than the aforementioned schemes. Split complimentary: Same as the previous color scheme, however you would also use the two colors either side of the secondary complimentary color. This mutes some of the starkness created by the previous scheme. Triadic : As the name implies this color scheme uses any three colors which form a triangle on the color wheel, equally spaced apart. Tetradic (or double complimentary) : In this case you pick a complimentary pair of colors (opposites), then a second pair to use in tandem. It's important to balance cool and warm colors for the right effect. For picking color schemes for things like quilting, starting at any point on the wheel and counting off three to five colors adjacent to one another makes for an interesting combination that provides variety and contrast, while avoiding the harshness of complimentary colors. A color wheel is a handy tool for everyone from software programmers to interior decorators and hobbyists. The next time you need to pick a color scheme, consider picking up a color wheel first!
