How to set the default theme for users in GitLab

Question

Is it possible to set the default theme for users in GitLab? Looking in the gitlab/gitlab.yaml I see no options to set a default.

---

Looking in the database, I see that there is a color_scheme_id. I'd rather not edit the database for every user.

    mysql> select id, name, theme_id, color_scheme_id from users;

+----+-------------------+----------+-----------------+
| id | name              | theme_id | color_scheme_id |
+----+-------------------+----------+-----------------+
|  1 | Administrator     |        1 |               1 |
|  2 | foo foo           |        4 |               4 |
|  3 | bar bar           |        2 |               1 |
|  4 | foobar foobar     |        2 |               1 |

There is a pull request in progress for that: PR 5116, by Izaak (John) Alpert -- (karlhungus).

It would add to the config/gitlab.yml.example file:

+    ## Default theme
+    ##   BASIC  = 1
+    ##   MARS   = 2
+    ##   MODERN = 3
+    ##   GRAY   = 4
+    ##   COLOR  = 5
+    # default_theme: 1 # default: 1
+ 

It just got pulled a few hours ago (Sept. 22d), so it should be part of GitLab 6.2

Update August 2018, 5 years later: the current default theme is 2 (see gitlab-org/omnibus-gitlab/files/gitlab-config-template/gitlab.rb.template.

### Default Theme
# gitlab_rails['gitlab_default_theme'] = 2
