Missing errorbox css in formal white theme

Moodle standard theme has reddish background-color css declaration in styles_color.css
.errorbox {
color:#ffffff;
border-color:#660000;
background-color:#990000;
}

.errorboxcontent {
background-color:#FFBBBB;
}
Current moodle standard distribution themes: chameleon, cornflower, metal, oceanblue and orangewhite have their own background colors for errorbox.
However, popular formal_white is missing .errorbox and .errorboxcontent colors.

Suggested fix for moodle\theme\formal_white\fw_color.css
add
.errorbox {
color:#ffffff;
border-color:#660000;
background-color:#990000;
}

.errorboxcontent {
}
or something to that effect...
