Stop using accent color for .osd
As per a #gnome-design discussion: accent is not very visible and not neutral enough, we should use white instead:
.osd progressbar progress,
levelbar block.filled,
scale highlight {
background: white;
}
.osd entry image,
.osd entry progress {
color: white;
}
.osd button.link,
.osd link {
color: white;
}
.osd textview text {
background: none;
}
.osd textview {
background: alpha(black, .5);
color: white;
}
.osd check:checked,
.osd radio:checked,
.osd check:indeterminate,
.osd radio:indeterminate {
color: alpha(black, .75);
background: white;
}
.osd switch:checked {
background: alpha(white, .5);
}
headerbar {
color: @theme_fg_color;
}
