Red, yellow, orange.

It might say something about Portra's colour signature or simply something about a scan's limitation but while it is easy to see which one is red, the orange appears much less orange than it is "in the flesh" so to speak. It looks more like a darker yellow.On the other hand the fruit salad looks to be spot on. I wonder if the colour of the material underneath is having an effect? Now I come to look at it closely I suspect this may be the caseIt is an interesting issue

Great photo to study. Thank you for sharing.
