Change to green background for confirmation message "User updated" in Forum profile

[tobifjellner]

When a user has submitted an update to the profile, the next screen will have a url on the format ​https://wordpress.org/support/users/[user-id]/edit/?updated=true

And a confirmation message will be shown as a banner directly above the profile. (see attachment).
Currently the background color is given as

div.indicator-hint {
    background: #fff8e5;
}

... which at least I perceive as being light RED.

I'd suggest that this background color is changed to a light green instead, for instance RGB EBFFE6. (Unless, of course, the same class is used for negative hints, as well...)
