+### How to customize the highlighting colors?
+
+The easytags plug-in defines new highlighting groups for dynamically highlighted tags. These groups are linked to Vim's default groups so that they're colored out of the box, but if you want you can change the styles. To do so use a `highlight` command such as the ones given a few paragraphs back. Of course you'll need to change the group name. Here are the group names used by the easytags plug-in:
+
+ * **Lua:** `luaFuncTag`
+ * **C:** `cTypeTag`, `cEnumTag`, `cPreProcTag`, `cFunctionTag`, `cMemberTag`
+ * **PHP:** `phpFunctionsTag`, `phpClassesTag`
+ * **Vim:** `vimAutoGroupTag`, `vimCommandTag`, `vimFuncNameTag`, `vimScriptFuncNameTag`
+ * **Python:** `pythonFunctionTag`, `pythonMethodTag`, `pythonClassTag`
+ * **Java:** `javaClassTag`, `javaMethodTag`
+ * **C#:** `csClassOrStructTag`, `csMethodTag`
+
+As you can see each of these names ends in `Tag` to avoid conflicts with the syntax modes shipped with Vim. And about the singular/plural confusion: I've tried to match the existing highlighting groups defined by popular syntax modes (except of course for the `Tag` suffix).

 ## Troubleshooting
 
 ### `:HighlightTags` only works for the tags file created by `:UpdateTags`
