Color theory is a science in itself covering a large number of definitions, concepts and design applications. Understanding color theory will help you to generalise the working of color on Web pages. Color wheel helps in learning groupings of colors that are harmonious together and other colors that might clash.

While many designers feel at ease designing a site for many users, those same designers might feel inadequate when it comes to selecting colors and graphics. The strategic use of color can turn a good website into a great website. Designing your blog or homepage with an eye for color helps to set you apart from your competitors, and produces a cordial environment.

Color Wheel

Sir Isaac Newton’s circular diagram of colors formulated in 1666, based on red, yellow and blue, is traditional in the field of art. Since then scientists and artists have designed several versions of this concept. Conflicts about the validity of one format over another continue to provoke debate. In fact, any color wheel which exhibits a logically organized sequence of pure hues has merit.

Primary Colors

In traditional color theory, the primary colors comprise of red, yellow and blue. These are the 3 pigment colors that can not be formed by blending any other color. All other colors are derived by combinations of these 3 hues. In HTML, they are presented as:

  • Red: #ff0000
  • Yellow: #ffff00
  • Blue: #0000ff

Whereas in CSS they can be recreated as:

  • Red: #f00
  • Yellow: #ff0
  • Blue: #00f

Secondary Colors

Orange, green and purple are secondary colors formed by mixing the primary colors; red with yellow, yellow with blue and blue with red respectively. They are represented in HTML as:

  • Orange: #ff9900
  • Green: #00ff00
  • Purple: #ff00ff

And in CSS as:

  • Orange: #f90
  • Green: #0f0
  • Purple: #f0f

Tertiary Colors

Tertiary ColorsYellow-orange, red-orange, red-purple, blue-purple, blue-green and yellow-green are tertiary colors formed by mixing a primary and a secondary color and they lie between the primary and secondary colors. They are represented in HTML as:

  • Yellow-Orange: #ffcc00 or #fc0 in CSS
  • Red-Orange: #ff6600 or #f60 in CSS
  • Red-Purple: #cc00cc or #c0c in CSS
  • Blue-Purple: #9900ff or #90f in CSS
  • Blue-Green: #00cccc or #0cc in CSS
  • Yellow-Green: #ccff00 or #cf0 in CSS

Colors, Tints, Shades, Value and Intensity

Colors, Tints, Shades, Value and Intensity Colors or hues have historically been split up into primary, secondary and tertiary colors. Color wheel shows all the tints, tones and shades so you can begin to realize the color possibilities you have in sight. Tint is the lightness of a color. You can make color a lighter tint by adding the color white. If you add the color black to a color, you make it a darker shade. When you darken a color you change its shade. The lightness or darkness of a color is called a value. Intensity is the brightness or saturation of a color. A color is more intense when it is a pure color and not mixed with white or black. When you mix a color on the opposite side of the color wheel to your color you change its tone.

  • Outermost band - tertiary color of red-orange (red + orange)
  • Second band - the tint of that tertiary color (white added)
  • Third band - the tone of the color (gray added)
  • Innermost band - shade on the print wheel (black added)

Harmonious Color Combinations

Harmonious color combinations use any two colors contrary to each other on the color wheel, any three colors evenly spaced around the color wheel forming a triangle or any four colors forming a rectangle. These combinations are called color schemes or color harmonies. Color schemes remain harmonious irrespective of the rotation of angle.

There are many theories for harmony. The following descriptions present some basic formulas.

Monochromatic Color Schemes

Monochromatic colors are all the hues, tints and shades of a single color. This scheme looks clean and elegant. Monochromatic colors go well together, producing a soothing effect. The monochromatic scheme is very easy on the eyes, especially with blue or green hues. While this scheme is the easiest to use, it doesn’t provide much excitement in a Web design for many designers.

Monochromatic Color Schemes

Analogous Colors

Analogous colors sit next to each other on the color wheel. For example: blue, purple-blue, and purple; or red, red-orange, and orange. Play with the hues and saturation of analogous colors to create a harmonious color scheme.

Analogous Colors

Complementary Colors

Complementary colors are opposite one another on the color wheel. By using colors that are opposite one another, including all the tints, tones and shades of both colors, you create color schemes that have intrinsically high contrast and so are brighter and more vivid. This scheme looks best when you place a warm color against a cool color. Some contrasting colors are red and green or blue and orange.

Complementary Colors

Split-Complementary Colors

The split-complementary color scheme is a variation of the complementary color scheme. In addition to the base color, it uses the two colors bordering its complement. This provides high contrast without the strong tension of the complementary scheme. It is the popular color systems among artists because of its versatility. The split-complimentary color scheme is often a good choice for beginners, because it is difficult to mess up. In order to maximize results avoid using warm low saturation colors such as browns and dull yellows.  The key is to use energetic, fairly aggressive split complementary colors.  Gray them out if the result is too aggressive until you get the desired balance.

Split-Complementary Colors

Triadic Color

By setting an equiangular triangle on the color wheel, you can create lively color schemes. This scheme is popular among artists because it provides strong visual contrast while keeping harmony and color richness. The triadic scheme is not as contrasting as the complementary scheme, but it looks more balanced and harmonious. The triadic color scheme also carries warm and cool colors, but one temperature will override. The most basic color triad is the three primary colors red, yellow, and blue.

Triadic Color

 

Tetradic Color Schemes

The tetradic scheme is the most diversified because it uses two complementary color pairs. The more colors you pick out, the more complex the color scheme. This scheme is hard to harmonize; if all four hues are used in same amounts, the scheme may look deranged, so you should select a color to be dominant or subdue the colors. However, one trick is to find a tint, tone or shade and adhere those regions instead of mixing pure colors and their tints, tones and shades.

Tetradic Color Schemes

Color Context

Its complex to see how color behaves in respect to other colors. Compare the contrast effects of various color backgrounds for the same yellow square.

Color Context

Yellow appears brighter against a black background and somewhat dimmer against the white background. In contrast with blue-green, it displays brilliance. Observe that the yellow square seems bigger on black than on other background colors.

Get Ideas From the Pros

Consider popular websites that you visit often. They have set their website with a few strategic colors. This is an excellent marketing solution - customers remember that Microsoft is blue and white, Greenpeace is green.

Your website is unique, and your color scheme should reflect that. By opting a dominant color scheme for your blog or home page, readers will know, on every page, that they are viewing your website.

Color Tools

Many websites offer tools for picking out complementary colors. These resources help you to choose not only a main color to brand your website, but also accent or highlight colors that are both eye-catching and attractive. By searching for meanings of colors, you can find common words and feelings that people generally attach to various colors and hues.

Keep your Design Reader-Friendly

If you are inclined to paint your entire site in bright, sunny yellow, coral, and neon orange, be careful to maintain visibility high. Ward off bad color combinations by applying colors with similar values. If you are having problems mixing your two-to-four chosen colors, try shifting the value of one or two colors. Take additional care while using light text on dark backdrops. Try to keep the main content of your website heavy in distinctive contrast. Highlight the sample text with your mouse. If you can read it more easily when highlighted, switch the colors of the text and the background.

Warm vs. Cool Colors

Complementary color schemes contain both warm and cool colors. The use of these colors puts up contrast. If you notice how the colors work on the wheel, you’ll soon find out that you can’t choose one color without choosing its opposite. If you pick a hot red, the opposite is a cool green. In case of cool blue-green, you’ll finish up with a spicy red-orange on the other side.
