A cravat. The reddish purple are definitely a yellow/blue combination. A dark royal purple can be just anthocyanin, but with anthocyanin vascular intrusions (AVI) resulting from Ae (anthocyanin enhancer) gene from I. aphylla. With dark royal purple (bluish tone) you will definitely need hot water test to be sure.

B Thanks, Chuck - all these discussions of pigments, info you've shared 
with us, but I never picked up that purple has yellow pigment.  Makes
sense of some of the seedling colors for me.

&lt;Combinations of yellow (alpha-carotene in most cases) with
anthocyanin blue can give a range of colours. Browns, reds and purples
are most likely.

The hot water test will take out water soluble anthocyanin leaving
oil soluble cartenoids pigments.

Purple is always a combination, as is brown and red. Without yellow
you get various shades of blue.

Richest browns are a combination of lycopene (pink) with
anthocyanin blue.
