change font colour in textbox with CSS when value is typed into box

[kmati]

I have a text box, which acts as a search box on my page. I pre-populate the field with the word 'SEARCH' which has a default text colour of #D6D6D0.Using CSS, is it possible to change the text colour to #FFFFFF when someone enters text in the box?\[code\]<input type="text" name="q" value="http://stackoverflow.com/questions/14503225/SEARCH" id="searchFieldText">#searchFieldText { background: url("/images/crmpicco/search_bg3.png") no-repeat scroll 0 0 #000000; border: medium none; color: #D6D6D0; float: left; font-family: Arial,Helvetica,sans-serif; font-size: 10px; height: 21px; padding-left: 0; padding-top: 3px; width: 168px;}\[/code\]
