Some blue dye, for e.g. like Robin blue is added to it to make it blue, so that black marketeers cannot sell it.
I think you can remove it chemically by distillation but in home its best to let it remain in shady sunlight for a few days and then decant it.

That is dye. And that dye is one of the main ingredient of nerve gas so leave it alone, They put that in there for a reason at the refinery, so that people would know what it is.

Blue dye. Try adding aspirin to remove it - it works with 'red' fuel sold tax free to farmers. So I am told!

if it's just dye you can easily remove it with distillation, but it depends what you want to use it for if you have to
