The spot pattern is the area, a pattern of distribution of pigment,
not the colour contained in the area. The inheritence of colour in this
spot  is independent ( not entirely true, but think of it this way for
the moment) from the other areas of the petals. It is a pattern, not a

A spot such as the purple spot on Ditto (MDB, purple spot on white),
consists of both cartenoid plus anthocyanin pigments in spot area to
produce a purple. Without the cartenoid  yellow, the spot would be
blue. With cartenoid pigment and no anthocyanin, spot would be yellow.
  You can have black spot on violet or purple , dark yellow spot on
light yellow, red spot on yellow etc. etc.

It  can get more complicated  when you combine spot pattern with
plicata.  Some very interesting  patterns.

Then there is the water soluble yellow, that when combined with a light
dosage of anthocyanin in spot area can give Green Spot and Tu Tu
Turquoise when anthocyanin is increased.

I got totally confused after your post about pumila spot genetics,

I was asking about <yellow> (i.e., oil soluble) pigment patterns, not

Isn't pumila spot an <anthocyanin> spot? From the little I found in The
World of Iris, it says anthocyanin.

Or is it somehow carried along as both anthocyanin <plus> yellow
pigments in the same spot from pumila?

Or is the yellow in pumila some kind of wierd yellow looking

Or is the yellow "spot" seen in SDBs actually from TBs and has nothing
to do with pumila spot?
