This is a long one, but it will change the bulk of the text color.
.post-info, .post-extras, .post-extras p a, .post-entry, .post-entry p, .post-entry li, .post-entry h4, .post-entry h5, .post-entry h6, .wp-caption .wp-caption-text, .gallery-caption, .wp-caption .wp-caption-text:before, .post-entry cite, .more-posts .page-title, .more-posts .notice, #more-posts-inner article, .comment-author, .comment-text p, #comments li.pingback .comment-text .edit-comment a, #calendar_wrap table td, #error404 span {
color: #A19090;
}
This takes care of normal text in the sidebar.
.sidebar-widget p {
color: #023F5B;
}
This is sidebar links
.sidebar-widget li {
color: #023F5B;
}
Post body font size
.post-entry {
font-size: 13px;
}
Sidebar font size will have to be done like this (change the 100% value)
#secondary {
font-size: 100%;
}
Links under title (cats, etc.)
.post-info a {
color: #ffffff !important;
}
I've likely missed some stuff, so give the above a try and then we'll go from there.
