@stephan_羅_德_帆 here’s a quick way to change it to blue if you can install a Chrome extension.

1. Install an extension allowing custom CSS such as Stylish
2. Add this CSS (copy it exactly) applying to URLs on the domain online-go.com:

.MainGobanView .players .ChatPresenceIndicator.online {
    color: #66f;
    text-shadow: -1px -1px 0 #aaf, 1px -1px 0 #88c, -1px 1px 0 #88c, 1px 1px 0 #66a;
}
