Documentation:
Colors used by `highlight-changes-rotate-faces'.
The newest rotated change will be displayed in the first element of this list,
the next older will be in the second element etc.

This list is used if `highlight-changes-face-list' is nil, otherwise that
variable overrides this list. If you only care about foreground
colors then use this, if you want fancier faces then set
`highlight-changes-face-list'.

You can customize this variable.
