How to override the 'post comment' font colour - comments plus


I need to change the font colour for the post comment button but I can't override it in my css.

This is what I've entered:

/***Comment Style - Edited - needs to be up top due to color for heirachy***/
#comment-providers input[type="submit"], #comment-providers a.button, #comment-providers a.button:visited, #comment-providers a.button:link {
border: 0!important;
color: #075C70!important;
text-shadow: none !important;

But the comments plus css also has !important next to it ... I tried putting the above code right up the top of the css file but that didn't work.

Any help is appreciated, I'm sure it's something really obvious :slight_smile:
