 For example, you can use `-D` to pass HTML color names to create a
 [“fire” themed variant][d2]:
 
     ./inskinerator -b default \
         -D text-color=lightyellow \
+        -D header-color=yellow \
         -D background-color=black \
         -D pri-accent-color=red \
         -D sec-accent-color=darkorange
+
+Note that we don’t necessarily have to override any of the late-defined
+colors, as they get the following defaults if not overridden:
+
+| Variable         | Late-Defined Value           |
+|------------------|------------------------------|
+| title-color      | $pri-accent-color            |
+| header-color     | $text-color                  |
+| footer-color     | $text-color + 40% lightness  |
+| ter-accent-color | inverse of $pri-accent-color |
 
 Or, you can use HTML RGB specs to create this [“PDP-11/70” theme][d3]:
 
     ./inskinerator -b default \
         -D text-color=\#000 \
+        -D header-color=\#B3003B \
+        -D title-color=\#622A5A \
         -D pri-accent-color=\#B3003B \
-        -D sec-accent-color=\#AE98CD
+        -D sec-accent-color=\#AE98CD \
+        -D ter-accent-color=\#B3003B
 
 Note that `background-color` isn’t needed: we got that from the default
 skin.  We can’t do without “black” for the text color, since the default
 uses [a very dark gray](/file/skins/default/vars.scss), not black.  But
 note also that we pass such strings through as-is, so that HTML’s
 allowance for the #000 shortcut works.
 
-You may also mix HTML color names and RGB specs to create this [mint
-green variant][d4] of the default skin:

     All skins allow overriding at least these variables:
 
         -D text-color=COLOR
-        -D background-color=COLOR
         -D pri-accent-color=COLOR
         -D sec-accent-color=COLOR

+        -D header-color=COLOR
+        -D footer-color=COLOR
+        -D ter-accent-color=COLOR
+
+    The final group are late-defined variables, defined by default in
+    terms of the first group.  If you don't override them, you get the
+    default definitions without duplicating their late definitions.
+    Thus, a "complete" variables-only override can be done by redefining
+    only variables in the first group.
 
     VALUEs for COLOR variables are any legal CSS color: 'white',
     '#abcdef', '#888', etc.
 
     Output goes to stdout if you don't give a file name via --output/-f.
