change line 14 to:

Expand|Select|Wrap|Line Numbers

document.bgColor="#"+c;

and line 27 to:

Expand|Select|Wrap|Line Numbers

 t+='<td bgColor="#'+color+'"><a href="#" onclick="bg(\''+color+'\')" > #'+color+'</a></td>';
 

kind regards

when you use it your mentioned way then you might see that the string is terminated too early and throws a JavaScript error, it would look like this:

Expand|Select|Wrap|Line Numbers

t+='<td bgColor="#'+color+'"><a href="#" onclick="bg('"+color+"')"

so after bg(' the string is terminated unless you escape the quote correctly

kind regards
