Changing background color in lists using HEX Codes Array In For Loop

[avil]

I was trying to show different hex codes as background in a loop for each section of a list.

 

Here's what I done

$rgb;
$rgb["c1"] = "ff4c54";
$rgb["c2"] = "ff764c";
$rgb["c3"] = "ffde4c";
$rgb["c3"] = "c7f25f";
$rgb["c4"] = "33c9f7";
$i=0;
$pargs = array( 'numberposts' => 10,'orderby'=> 'comment_count', );
$myposts = get_posts( $pargs );$max_count=0;
<ul>
foreach( $myposts as $post ) :  setup_postdata($post); 

<li style="width:300px;background-color:#<?php foreach($rgb as $color => $hex) {
    echo $hex[i];
    $i++;
}  ?>">
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a> - </li>
<?php endforeach; ?>
</ul>

 

Ending up with just the white background.. and no change in the background colors.

 

Kindly help

If you look at your actual output, you should see the problem. View the source in your browser.

 

You also have some php code not in php tags.
