+Subject: [PATCH 2/9] Blank the screen with color 0, add third color for failed
+ logins
+
+- Adds another color in config.def.h, COLOR_INIT
+- Renames the colours from numerical ones to ones with meaningful names;
+  COLOR_INPUT for when there is content in the input buffer and COLOR_EMPTY
+  for when the input buffer has been cleared (backspaced or a failed attempt).
+- Ensures XFreeColors frees the right number of colours. This is now derived
+  from the size of `Lock->colors` rather than being an integer literal.
+- Makes slock exhibit the behaviour described by Markus
+
+The default colours are the same as the ones slock currently uses, with the
+exception of the new color, which I have set to red, as it indicates someone
+has either failed an attempt to unlock, or that they have entered input and
+erased it all.
