Jonah, yup, many of my blood oranges do not have much red flesh color in my location. One time the Vaniglia show a little streak of red in the flesh. Yes, I would like to see a photo of your fruit.
I have the Rhodes Red Valencia, Smith Red Valencia, Tarocco #7 blood orange, Bream Tarocco blood, Cara Cara blood orange, Boukhobza blood orange, Maltaise Demi Sanguine blood orange. So far I don't think any of these gives a nice red flesh for me. Even the Valentine pummelo hybrid only shows the red flesh once in a while. I only have one unknown seedling pummelo (Tony #1) that always shows the nice red color flesh regularly.
