Re: HYB: color patterns

One way to research this involves looking at pictures where both anthocyanin  and carotene is distributed in the same pattern. Then look at parentage and see what patterns are there. Also look at offspring and check again how the  oil based and water based pigments are distributed. If you can demonstrate , at least to your own satisfaction, that they are both controled by the same underlying genetic factor then you design a way to put it to the test. That is design a cross that will test it out.
This is how I arived at the test cross of Rusty Dusty x Light Beam . Actually I made at least  12 test crosses of LB with various plicatas. There were only two with seeds and only the one cross that had enough seedlings to provide me with useful data.  
Now for more crosses with different suspected "Yellow plicatas"" 

You have an interesting proposal there but I  don't see anything that would convince me at this point in time.  Do some more reseach and see what you come up with.

Best luck

Does this mean that yellow/pink based amoena umbratas (white standards
and fall rims, yellow or pink fall centers) pigment distribution might
be controlled by the same whatever it is that controls distribution of
pigments in anthocyanin based amoena umbratas (recessive amoenas, white
standards and fall rims, blue fall centers)?

If these patterns also both come from I. variegata, it seems likely?

And might there be a yellow/pink version of dominant I(s), controlled by
the same factor?
