The border colors can be done using CSS classes.
input.failed {border: 1px solid red;}
input.successful {border: 1px solid green;}

The validation would be Javascript, but you're not going to find an answer to this since the validation steps will depend on the input you're trying to validate.

You would want to do something like this: (This uses jQuery)

<script type="text/javascript">
$('.number_validate').blur(function(){
if($(this).val() > 0){
$(this).css('border','1px solid #00ff00');
}
else
{
$(this).css('border','1px solid #ff0000');
}
});
</script>

<input type="text" class="number_validate" name="textbox" onblur="validate()" />
