What I did:
Filling a fluid wagon with a liquid from a mod.
In my case it was frost extract from Frost Bitter. Just for testing.
What I expected:
wagon.color = game.fluid_prototypes[fluid].base_color
In my case it was {r=0, g=0.10, b=0.8}.
flow_color is fine too.
What I got:
Nothing. Color not changed.
P.S. With vanilla fluids it works fine.
UPD
I found fluid color data in __Automatic_Train_Painter__/color/database. Looks like you using only colors from this table and ignore game.fluid_prototypes. BUT WHY???
