I come back to the Exiled Lands about once a year, usually with a pack of new and old friends.
…I usually do camp duty like making food and drink and at some point when I’m doing my brewing I always get thrown off by those berries and their mixed up colors.
Apparently this was a thing in like… 2019! 2018? By Crom!
My uneducated brain just can’t comprehend how the blue seed make da red juice!
…maybe this time I should pray to Mitra. Crom never listens 
It works in real life too. At least in dye. I have friend who dye cloth/threads and and uses all sorts of natural stuff. And sometimes you get very weird color out off complete different color.
If I remember right birch (Betula spp.?) leaves (green) can give you bright yellow.
And old school tanning that uses for example willow (Salix spp.) bark is not brown but greenish and makes hide brown.
And what comes to berries. Flesh inside can be completely different color than the outer layer.
But in game logic. You are right. Straight forward logic makes things - logical.
After all this time, I had not noticed that .. until just now.
But just for some context here is something from the real world.
These are the seeds from the Holly plant.
And these are the berries from the Holly plant.
Considering that they are.. well.. poisonous I rather doubt anyone is making any “pulp” to drink from them so I have no idea what that looks like, but it’s likely to be more like the berries than the seeds. 
So the seeds from a plant looking quite different to the berries of the same plant is not really all that unusual. The same is true for fruits, how many apples have seeds that look like the apples that contain them?
