[THEME Sensitive by WP Eden] Change Link Color in CSS Style Sheet

Hi,

I am using the Sensitive theme by WP Eden for my website and I cannot figure out how to change the colors of the web links (regular color, visited color, hover color). I am not very familiar with CSS but I had added the following to the style sheet:

<STYLE type=text/css>
A:link {
COLOR: green
}
A:visited {
COLOR: #000000
}
A:hover {
COLOR: #ff0099
}

</STYLE>

For some reason, my unvisited links still come up “Blue”, the links are “Blue” when I hover over them, and the visited links tag is the only part that works(see https://www.liteworkevents.com/wordpress2/upcoming-events).

Can someone help???

Thanks!
