CSS Tweaking help

In a few of my sidebars/footer areas I list events and the event name should be a green colour.

See: http://www.pleinairbc.com/contact/

I tracked it down to this looooooooooong string of css (see below) that if I change the color to “none” then the preferred coloring shows.

However, that string is too long and I don’t want to effect other parts of the site, just the sidebar listing.

Can you help me with narrowing down the css?

.main_color .meta-color, .main_color .sidebar, .main_color .sidebar a, .main_color .minor-meta, .main_color .minor-meta a, .main_color .text-sep, .main_color blockquote, .main_color .post_nav a, .main_color .comment-text, .main_color .side-container-inner, .main_color .news-time, .main_color .pagination a, .main_color .pagination span, .main_color .tweet-text.avatar_no .tweet-time, #top .main_color .extra-mini-title, .main_color .team-member-job-title, .main_color .team-social a, .main_color #js_sort_items a, .grid-entry-excerpt, .main_color .avia-testimonial-subtitle, .main_color .commentmetadata a, .main_color .social_bookmarks a, .main_color .meta-heading > *, .main_color .slide-meta, .main_color .slide-meta a, .main_color .taglist, .main_color .taglist a, .main_color .phone-info, .main_color .phone-info a, .main_color .av-sort-by-term a, .main_color .av-magazine-time, .main_color .av-magazine .av-magazine-entry-icon {
