Brian, here is my moro blood. It fell of the tree when I was trying to put cover over for the last cold night. I think it wasn't ripe yet but also it may not be like yours when it's fully ripe.
Cara cara is not to my knowledge a blood orange. My inground cara cara in Beaumont texas never had the orange flesh in the fruit. In September before any cold weather the flesh was red. The color is the main reason I grew cara cara. Standard navel oranges never get a very good color in SE Texas, even with cold weather. I suspect your cara cara was mislabeled and is some common unknown strain of navel orange.
Cara cara is not a "blood" orange.
Cara Cara, whether grown in Colorado or Florida should turn pink. Because the coloration of the Cara Cara is caused by the chemical Lycopene, it will produce pink colored fruit when grown at any location or in any temperature range.
