The pale blue with dark beards are of this type.

Aha! That makes sense. Thanks so much, Chuck. Really neat work you've
done with this stuff.
I had been wondering if this was Ae type anthocyanin, but wasn't able
remember whether you'd said Ae could be present if the regular
anthocyanin isn't there. Looking at the petals, they have a very
different color quality from others with yellow and blue that I've
soaked here where the blue has been easy to remove in alcohol. Not
what it is about the color that made me think 'black'.
So this is what Ae looks like on a yellow flower where 'blue' is
suppressed. Cool. Can you have a white flower with Ae inclusions. no
anthocyanin dissolved in vacuoles, no yellow or pink, just Ae
inclusions? What would it look like?
So much white in the ancestry on both sides, a little challenging to
understand yellow in this kid - all the sibs are very clean white with
varying reddish to bluish purple bands on the falls.
Not a lot of pigment in standards or falls of this one, but sure is a
lot of pigment in that beard!
<In a number of flowers of this type of shading, the anthrocyanin is
Ae form. that is a solid clumps inside vacuole, rather then as
dissolved in vacuole. thus doesn't come out until petals are crushed or
destroyed as in hot water.>
