Changing ContentLink color can influence user click-through rate (CTR) as well as assist in maintaining a coherent look and feel throughout your site:

1.  Login to your account via the Kontera Publisher Center and enter the "ContentLink Setup" tab. 

2.  Pick the color that you feel best suits your site's color scheme and design from the color palette window.

 
3.  Your selection will automatically be reflected in a new tag created for you in the window below.

4.  Copy and paste this tag right before the </BODY> tag on every page on your site where you want ContentLinks™ to appear.

You may want to experiment with different colors to see if this has any effect on your click through rates.
