Different coloured links: author and publishing date

I’m using the Read template from the site library.

I did your tip and it worked for the post title on the homepage:

.wp-show-posts .wp-show-posts-entry-title a {
    color: #f00;
}

.wp-show-posts .wp-show-posts-entry-title a:hover {
    color: #0f0;
}

I’d also like to ensure the author’s name and publishing date are the same colour as the wp-show-posts-entry-title. I tried to play with the CSS using .author-name and .wp-show-posts-entry-date but have had no luck. Any tips? Thanks!
