In FS22 I have not encountered such problem. just in fs25: quinoa first and now sesame...
I am worried my orchards will have the same problems... I will try to get GE (and the game or game files if it works only with them) on the virtual machine to see what I can do, but I have no clue...
As I thought that's really a giants limitation, I tried
thundrfs.itch.io/fs25-default-types
and color was there, without editing the mod itself. So if you go deeper and customize it for your map you should optain a good result as you don't use so much vanilla crops ressources.
