RE: Yellow And Pink

Here is a photo of Chariots of Fire. Rather interesting colour as falls are 
orange, lighter in centre. Standards are pink with an orange edge.
Also a photo of standards and falls after an extraction in warm alcohol. Warm 
alcohol removes anthocyanin, none in this case, and carotenes, but not 
lycopene. As you can see, after extraction, is that the yellow pigment was 
only on the rim of the standards whereas lucopene is evenly distributed,. Two 
different patterns, related pigments. I checked, the yellow is oil soluble. 

There are many examples of this but this is the most dramatic.
Consider the yellow flowers with red beard. 
There are also many examples of flowers with  different distributions of 
these two pigments.

There was evidence of two pathways to production of beta-carotene and not all 
biologists/chemists acept that beta-carotene has to come from lycopene.  
There is some evidence that in some cases it can derive from the lycopene 
precurser. I suspect that with the right flowers, such as with Iris, we may 
find evidence of that.
 The dominance chain of pink and orange can be easly tested. Yellow is 
dominant over pink and orange as t is recessive and pink and orange are tttt 
plants. But what about the yellows with orange beard crossed with orange or 
pink. That is a different story.
