Now believe it or not colors, according to the experts, can have a profound effect on us, either on a negative or positive basis.

So for the reason I have just given, I have listed below the most popular colors and the affect they are meant to have on us.

Colors are mostly used in the presentation of online sales letters, this can add impact and or interest to the sales letter, as well as having a positive effect on the reader, providing the right colors are used of course.

You can also, by using the color chart below, choose which color would be most suited for your headline text etc.

Yellow: Is considered a warm cheery color, it is also the most visible color and is considered one of the most attention getting, however, it can be fatiguing especially on computer monitors. So to get attention, use yellow but sparingly.

Purple: Is a color that signifies royalty and wealth, and is said to represent wisdom and the exotic. You could use purple in your sales letter promoting quality high price products.

Brown: Is a natural earthy color, it gives a sense of strength and reliability, it can give a feeling of comfort, security and warmth, it can also be seen as sophisticated.

Orange: Is an energetic color, it induces feelings of excitement, enthusiasm and warmth, its also a very strong attention grabber. A good color to use throughout your sales letter for any product.

Pink: Is associated with love and romance, it has a calming affect. Could be good for cosmetics, ladies fitness plans etc.

Green: Is the color of nature, it has a calming effect and gives a sense of tranquillity, it is also a symbol of health and fertility. Good for products on herbal remedies, Healthy eating etc.

Blue: Is a productive color, and a popular color for men but is not an appetizing color as far as food is concerned. Could be used for manly products, but not for herbal remedies, Healthy eating etc.

Red: Evokes strong emotions of love, comfort and warmth,it can create feelings of urgency, power and excitement. A good color for headlines and sub headers throughout your copy.

Black: There's not much one can say about black, except that it should always be the color of your copy on a white or off-white background.

So there you have it, now as I have already said, colors can add interest to your sales letter, and there’s nothing bad about adding interest is there, so use colors but don’t overdo it, try and aim for a nice balanced layout.
