change link color css

Hi,

Im trying to format the style of the text links from the output of listing blog post [display-posts posts_per_page=”3″]

The links are white and centered. I have added the following css code to my theme, which changed the bullets to green and alinged the text left, but did not change the color of the links. They are still white and underlined. Can you tell me how to adjust the code below to make the link color green #36ae7c

/* display post align left */
li.listing-item {color: #36ae7c; text-decoration: underline; text-align:left;}
