is_category within a loop

Hi guys.

I have a is_category ‘news’ going on, then a loop. Within the loop I want each post to display slightly different depending on which sub category of ‘news’ it is in.

I thought this would be easy…

<?php if (is_category('news')) :?>
	<h1>Latest <?php single_cat_title(); ?></h1>
	<?php while(have_posts()): the_post(); ?>
		<?php if (is_category('news-1')) :?>
			<p style="float:right;">Whatever if news-1</p>
		<?php elseif (is_category('news-2')): ?>
			<p style="float:right;">Whatever if news-2</p>
		<?php elseif (is_category('news-3')): ?>
			<p style="float:right;">Whatever if news-3</p>
		<?php endif; ?>
		<h3><?php the_title(); ?></h3>
		<p>News article posted on: <strong><?php the_time('jS F Y') ?></strong></p>
		<?php the_content(); ?>
	<?php endwhile; ?>
<?php endif; ?>

It appears to just ignore my is_category within the loop though.
