I need to change the font color.

I have the following:

   var clr="green";

    <font color=clr>' + onlineff + ' </font>

The font color does not change to green. Just wondering how this could be fixed.

Don't use <font color=. It's a really old fashioned way to style text and some browsers even don't even support it anymore.

caniuse lists it as obsolete, and strongly recommends not using the <font> tag. The same is with MDN

Do not use this element! Though once normalized in HTML 3.2, it was deprecated in HTML 4.01, at the same time as all elements related to styling only, then obsoleted in HTML5.

Starting with HTML 4, HTML does not convey styling information anymore (outside the element or the style attribute of each element). For any new web development, styling should be written using CSS only.

The former behavior of the element can be achieved, and even better controlled using the CSS Fonts CSS properties.

If we look at when the 4.01 standard was published we see it was published in 1999

where <font> was officially deprecated, meaning it is still supported but shouldn't be used anymore as it will go away in the newer standard.

And in the html5 standard released in August 2014 it was deemed obsolete and non conforming.

To achieve the desired effect use spans and css:

function givemecolor(thecolor,thetext)
{
    return '<span style="color:'+thecolor+'">'+thetext+'</span>';
}
document.write(givemecolor('green',"Hello, I'm green"));
document.write(givemecolor('red',"Hello, I'm red"));
body {
  background: #333;
  color: #eee;
}
