This utility will help you select a matching 6-color palette for your website.
Define a single color that you like. Matching colors will be calculated.
Click a color in the palette to promote it to the primary color.

I like this color:
6-color matching palette:</div><script>pl(170,"red","r");pl(200,"green","g");pl(230,"blue","b")</script><div class=s id=sw style="position:absolute;left:316;top:170;height:81;width:82;background-color:black;"></div><div style="position:absolute;left:20;top:290;"><table cellspacing=10 cellpadding=0><tr><script>ps(0);ps(1);ps(2);ps(3);ps(4);ps(5);</script></tr><tr><script>ph(0);ph(1);ph(2);ph(3);ph(4);ph(5);</script></tr></table></div>

<h1>About this page</h1>
The color selector on this site was submitted as an entry for the Danish 5KB (5.120 bytes) web competition in 2001.
Given the nature of the competition ?allowing only for 5.120 bytes to be used in total! ?I was not able to make it cross-browser compatible at the time. Despite the lack of compatibility beyond IE, the tool won the competition.
A lot of enthusiastic people around the World have not only made it more compatible, but also added even more features. <a target="_blank" href="http://www.google.com/search?q=colormatch+5k">Google will guide you to them!</a>
If you for some reason want to get in touch with me, please use the contact form at my site <a target="_top" href="http://port80.biz">Port80.biz</a>. ?Best regards, Kim Jensen aka kim^lwx
