No, because as you're using an !important rule in the stylesheet, it supercedes the inline style (unless, of course, it has an !important rule itself). :)
I use this rule, for the comment bar colours:
.talk-comment td+td {
background-color: #bcc4bc !important;
}
You know what would be awesome? A CSS guide like this one. I'm not volunteering for it, though :P
