Chuck, if you have time, one more time re: pigment extractions, yellows, orange.
First is hot water to get rid of anthocyanins, right? Or does that also removed one of the yellow pigments? 

Second is alcohol, which definitely removes one of the yellows.
Third is oil (lamp kerosene is what I use, 'cause it's available) which ....uh, removes more yellow? Ok, this is where I forget what that does. After the kerosene soak. usually all I see left is the tangerine pigment (either pink or red) left in the beard (if there is any), plus some yellow in the thicker part of the petal near the beard. 

Some results - skipping the water extraction, just using the alcohol step,
- Mary Lou's pink HoM seedling: some yellow in the alcohol wash, pink left in the petal
- Gold seedling from TEA LEAVES X GOLDEN PANTHER: yellow in the alcohol wash, yellow in the petal, t in the beard. I don't have GP any more to see what it does 

- HoM - yellow in alcohol, yellow in petal, no t in beard
- pale orangish seedling from GOLDEN APPLE X CRYSTAL GLITTERS: yellow in alcohol wash, pink in petal, t beard.
If it were 'true' orange, would the alcohol wash look yellow, petal still look sort of orange after alcohol wash? i.e., pink plus yellow oil soluble?
Since the archive search engine doesn't seem to work for "and", maybe having the words 'orange pigment extraction' all together will make it easier to find the thread next time.
