As we all know, there are a variety of ways to advertise your company. Everything from television commercials to highway billboards to magazine ads have been employed by companies from all over the world to assert their brand's relevance in the general public. Of course, some types of advertising are more expensive than others. And some types of advertising are more effective.

One factor that assists in the effectiveness of advertising is the colours used in the ad. Choosing the right colours should never be overlooked as an unimportant task. Deciding upon what the right colour is for your brand has everything to do with type of product or service your promoting.

Sherry Holetsky of wiseGEEK.com discusses the purposefulness behind the various colour schemes that can be used. ?The best colors for advertising are those that make people comfortable or stimulate their senses,? she writes.

According to Holetzky, in an effort to promote warmth, comfort and relaxation, restaurants often choose deep burgundy and burnt orange as colours for their advertising. These hues, apparently, connote the concept of enjoying a leisurely meal in a comfortable and pleasant environment.

Hot colours, however, are generally used when promoting fast food. Bright red and yellow indicate a fire-like excitement around the brand. Writes Holetzky: ?Virtually all logos, advertisements and menus of fast food chains feature these colors, which is no accident. Companies rely on the extensive research that has been done in this field, to get the most for their advertising dollars.?

By contrast, companies advertising health products often employ cool colours such as green and blue. Blue, says Holetzky, conveys tranquility and is most often associated with water to represent a life force. Interestingly, she notes that the colour blue can actually slow a person's heart rate and reduce appetite ? a reason why restaurants tend to stay away from blue.

When it all comes down to it however, black and white are often seen as the best colours for advertising. They are known to signify power and professionalism, says Holetzky. Sometimes adding a ?splash of colour such as red? is incorporated to emphasize the simplicity of the ad, giving it a new attitude, so to speak.

Good advertising is key to strong sales. Choose your colours wisely, and you could be seeing a lot more green.
