feat: allow users to pass ring_color param (anuraghazra#2075)

* fix: prevent crash if undefined color is passed to func fallbackColor

* feat: allow users to pass ring_color param

Before this commit, the ring color was always equal to the title color.
This commit allows the user to pass a ring_color property to allow him
to style the ring color the way he pleases to. If no ring_color is
passed we default to the title color.

* docs: improves ring color documentation

* fix: improve code style
