+### Colorscheme
+
+If you want a predefined color scheme, then you may add the json from
+the file `colorscheme.json` into the settings `textcolors` and/or `backgroundcolors`
+in the plugin settings. This can be done by e.g.
+
+```
+UPDATE config_plugins
+SET value = '<json_string>'
+WHERE plugin = 'tiny_fontcolor' AND name = 'textcolors';
+```
+
+### Multilanguage support
+
+Color names may also use language tags for the color names. Text filters
+are applied. For example setting black and white with German and English
+labels would look like this:
+
+```
+[
+    {
+        "name": "<span class=\"multilang\" lang=\"de\">Schwarz</span><span class=\"multilang\" lang=\"en\">Black</span>",
+        "value": "#000000"
+    },
+    {
+        "name": "<span class=\"multilang\" lang=\"de\">Weiss</span><span class=\"multilang\" lang=\"en\">White</span>",
+        "value": "#ffffff"
+    }
+]
+```
+
+The value of the `name` property can be copied as it is, in the admin settings area.
+
+The name of the color is used as a tooltip in the editor when hovering
+over the appropriate color square.
