Is it possible to get some pictures under pink lighting?
That would help clear up any ambiguities I'm sure ,
but that was the only decent fruit I had this season...and I just took the pic under my kitchen light. Which is just a standard bulb , not really designated as a specific color.
If you look at the edge of the fruit, the one with supposed pink flesh has a much thicker layer of red pigment, which fades to light pink into carpels.
Another factor that determines pulp color is stage of ripeness, I have two pics of big red to compare, one is not over ripe and the pulp color is more white, but when it gets over ripe, as in my second pic of big red, it gets translucent, especially near the rind, and starts to show some color, but not necessarily pinkish pingment.
The fruit that was supposedly pink, was not over ripe, it was perfectly ripe, and photographed immediately after being bisected
what i've learned from my 3yrs of searching for a pink fleshed squamosa, is...they do exist, but the pigmentation is not as intense as you'd see in A. macroprophyllata, and A. reticulata, with bright pink, and deep red colors....the sugar apples that have pigmented flesh, seem to be on par with "selma" cherimoya, at best, in terms of color intensity....but there does seem to be variation, even within the red fruited varieties of squamosa, with some having white flesh, and some having pink tinged flesh.
