CSS attr() で color 指定ができない・・・ ならば

More than 3 years have passed since last update.

attr - CSS | MDN

Syntax
/* Simple usage */
attr(data-count);
attr(title);

/* With type */
attr(src url);
attr(data-count number);
attr(data-width px);

/* With fallback */
attr(data-count number, 0);
attr(src url, '');
attr(data-width px, inherit);
attr(data-something, 'default');

.members .member:before {
    position: relative;
    font-family: "FontAwesome";
    font-size: 18px;
    font-weight: lighter;
    content: '\f2be';
    color: attr(data-color color);
    margin: 2px;
}
