With https://gerrit.wikimedia.org/r/806237, (T303571, T310679), links to contributions pages of users without any contributions get the class "mw-usertoollinks-contribs-no-edits", instead of the class "new". The colors, however, should still be red as before, with "color-link-new" and "color-link-new--visited".
In Minerva on the mobile platform, the mentioned links with .mw-usertoollinks-contribs-no-edits are blue. (I use Safari with iPadOS 15.6)
