I’m talking about links of course, the ones on your site. They have blue as a default color for a very good reason. The exact reason why blue was originally chosen to be the default color for links is no doubt lost in the history of the original Mosaic browser. Thankfully the only thing that you need to know is that people are used to blue links. That’s the color that they are used to more than any other.
Some would argue that fancy stylings the use a light off-Grey or some other color that suits their preferred color scheme is somehow better but when it comes to sales pages I disagree. The links are there because you want people to recognize them as links and click on them so that they can progress closer to the point of closing a sale. There are, of course, some exceptions to this rule. However if in doubt, go with Blue for links.
Partly because of those original default colors and partly because it’s easier to see, most people instinctively respond better with blue even if they respond well to other colors.
If you have any doubt it’s easy enough to test different designs. Try one with whatever color scheme you prefer and then try the same page with a simple white background, black text in an easy to read size and font, and finally make the links blue. Not off-blue, or blue-grey but just plain old hexadecimal #0000ff Blue.
Just copy this code and paste it on your site where you want the link to appear:
