    Textarea background color change

    I have a form that I have put together which needs the text area results to have either a font color change or a background color change based on the click of a radio button. I need to have 4 different color changes. Here is my current coding.
    Thanks in advance,

    Code:
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

    <script type="text/javascript">
    function check(winddirection)
      {
      document.getElementById("forecast").value=winddirection;
      }
    
    
    
    </script></head>

    Question More information required ...

    Questions:

    1. Where is the <textarea> you wish to color change (or is it just the 'text' box)?
    2. What are the colors you wish to change to and under what radio button conditions?

    BTW: As an un-informed user, it might be nice to know what each cloud type looks like.
    Possibly display small image of clouds when selected?

    I NEED THE ON CLICK RESULT TO BE A DIFFERENT COLOR FOR EACH FOR A TOTAL OF 4 DIFFERENT COLORS
    The blue text is where the text results will display.

    Thumbs up

    Try this ...
    Code:
    function check(winddirection)  {
      document.getElementById("forecast").value=winddirection;
      var cloud_color = 'white';
      if (winddirection.indexOf('Excellent') == 0) { cloud_color = 'yellow'; }
      if (winddirection.indexOf('Very Good') == 0) { cloud_color = 'green'; }
      if (winddirection.indexOf('Good') == 0) { cloud_color = 'lightblue'; }
      if (winddirection.indexOf('Fair') == 0) { cloud_color = 'orange'; }
      document.getElementById('forecast').style.backgroundColor = cloud_color;
    }
    Change colors as needed ... could also be #rrggbb settings.
