+# Check Your Current Color Scheme
+
+Vim ships with a number of different color schemes. There is also a plethora
+of color schemes built by the open source community. If you'd like to know
+what color scheme you are currently using, you can check with
+
+```
+:echo g:colors_name
+```
+
+So more details at both `:h g:colors_name` and `:h colorscheme`.
