What I was saying is that it is basically a pale pink amoena with rose
anthocyanin stripes.


There are five main groups of anthocyanins.
pelargondin, Peonidin, Cyanidin, Petunidin, deplphinidin, and Malvidin. In bearded iris by far the most common anthocyanin  pigment is delphinidin in its many forms with sugars and hydroxyls connected at two different atatchement points and the chemicals attatched to these attatchments. Of the other pigments the only other one to be found is Malvidin and it had only been found in the cultivar of Frank Adams, and not identified as being in any other cultivars.  Malvidin is found in fushias and many other flowers, but always in conjunction with delphinidin. The pigment floridor had also been found in the diploid Florador and a couple of seedlings but so far has never been identified in any tetraploids. (WOI pg 360-364)

So,  the anthocyanin pigment is any of the forms of deplphinidin which can have many shadings but all violet/purple, not too wide a range. A lot of intensity diferences though.

There are also the flavanoids, which are water soluble and as I discovered via kitchen chemistry, more common then previously thougt. These are cream and light yellow and can really change the tone and  the appearance of the cartenoid and the light shades of anthocyanins.
