The best way is to ignore the dye, and reload them. It will have no effect whatsoever on function.

If you want to see if the die comes off try some MEK, Acetone, or mineral spirits on a rag, or throw a few in a little container and let the soak.
I'm not seeing any blue in the photo. I am seeing some annealing indications which will give you a blue band depending on how hot the brass was heated. It's caused by oxidation. This will normally come off using a tumbler with walnut nut hulls or a wet SS tumbling with soap. Remove all the nickle if you go wet. Also scan the brass with a magnet to make sure there is not brass plated steel.
^^^This, but how do you know the blue is from dye? I tumble found range brass to make sure it is clean and won't scratch my dies. Tumbler medium is cheap compared to dies. One can use pet bedding like corn cob and crushed walnut available at Walmart that is much cheaper than commercial reloading medium. In a pinch you can use rice. I would tumble and see if the "dye" comes off. Very few things will tarnish Nickel blue, but some acids do. Could be from a previous reloader using some form of agent containing acid to clean the brass.
The Border Patrol and some other LE agencies issue dyed training ammo to their officers.

From the shade I'm seeing it could be Dykem blue. Machinists use it for layout. Naptha or acetone will remove Dykem with no effort.Yeah hard to see in the pic of the mixed cases and it's more purple. I think it's primer sealer though.
