 **vtcol** knows two ways of loading a color scheme: From a set of predefined
 palettes or by loading it from a definition file. The latter accepts input in
 the format supported by setcolors_. (Not much effort has been put into ensuring

 directly from a definition file is accomplished by specifying the ``--file``

 To show the current scheme of the active console use the ``get`` subcommand: ::
 
-    $ vtcol get
+    $ vtcol colors get
     solarized_dark
 
+With the ``-base64`` switch ``vtcol`` outputs a binary representation of color

 It is also possible to use vtcol to switch between two themes by means of the
 ``toggle`` subcommand. E. g. to cycle between “dark mode” and “light mode”: ::
 
-    $ vtcol toggle solarized solarized_light
+    $ vtcol colors toggle solarized solarized_light
 
 To view a scheme’s definition, for instance in order to verify that **vtcol**
 parses it correctly, use the ``dump`` command. ::
 
-    $ vtcol dump default
-    $ vtcol dump ./schemes/solarized
+    $ vtcol colors dump default
+    $ vtcol colors dump ./schemes/solarized
 
 This will print the color definitions contained in the scheme; if the specified
 name does not resolve to a pre-defined scheme it will be interpreted as a file
 name instead.

 pragmatic reasons but that palette may not harmonize with everybody’s taste.
