dazzling indigo berries,
in an indigo-filled bush
lying underneath
the dazzling indigo sky.

gleaming indigo eyes,
and veiny indigo veins.
robins fill their twiggy nests
with indigo eggs.

many-a worrisome creatures
lie underneath indigo waters,
only found at the very bottom
of the indigo ocean.

though i suppose you could argue

that indigo is more violet,
if anything.
