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.

Hi Chuck,ÂI have no trouble believing that the yellow pigment is still
present, but couldnât yellow + blue-violet (âhorticultural blueâ) give
just about any color in the iris spectrum, depending how strong each
pigment was and the exact hue of each? ÂFrom:

The bright yellow of Billionaire is there with the blue of delpninidin.
The two combined gives you purple.
To check this out for yourself, put a petal of this seedling into
boiling hot water. the anthocyanin delphinidin is water soluble. The
yellow isn't. so after the anthocyanin has dissolved, you will see the
yellow. May need a couple of hot water treatments to get all the
anthocyanin disolved.

Just opened, parentage is Billionaire x Now see This. strange how the
bright yellow color of Billionaire has become totally recessive
