Just a quick google-
The two antifreeze types are not chemically compatible. They can chemically react with each other causing a viscosity increase and even gelling in the cooling system. This will render the coolant less effective and can even damage your cooling system. Don't ever mix the two coolant types.

Haven't seen any red anti-freeze since back in the 1960's. It was supposed to be a longer lasting anti-freeze and didn't require changing annually like the green stuff. But, if I remember correctly, it cost more. Thinking it was maybe a zerex product that came in a round metal can. I used it some.

RV antifreeze is pink to light red. Dexicool was kind of red if I remember right. In either case, those should not be mixed with plain old green antifreeze.
You could post some pictures of the containers of red antifreeze you picked up so people can see what it is, or post the name and info from the container so they can look it up. If you don't have any info beyond it is red antifreeze, it is best not to use it in anything.

David, I believe what you are referring to in the 60's was Dupont Telar antifreeze

I wouldn't try it. There are 2 type of greem antifreeze one that will mix with any other color and one that wont go to your local napa or other auto part sore and ask for universal antifreeze (the napa number it 1ext for concentrate or rtu1ext for premix)

It will be fine. As you've no doubt discovered, the old silicate antifreeze has pretty much disappeared from shelves, and has been replaced with generic 'compatible with all types' antifreeze. When you mix organic additive technology (OAT) antifreeze with silicate antifreeze, the OAT loses its long-life properties, but the result is no worse than if you added more silicate antifreeze.

What KIND of "red antifreeze?" What does it say on the bottle?
Without that information none of these answers are valid. One or more of them is certainly correct, because you got all the possible answers to your question. WHICH one though?

Then I would put/mix equal amounts in a saucepan and let sit for a week. If it did not go funky I would then heat it up to 250/300 degrees on a hot plate.
Do the above outside and stand up wind!
Wear protective gear as who knows what else the junkyard guys dumped in with that red stuff.
But honestly, why use the stuff even if it was free???

Well then it could be just about anything... up to and including stuff that isn't antifreeze.
Put it in something you don't care about, then it won't matter if anything happens. Or, use it as tire ballast.

The only thing I would put it in is my 5 gallon pail mouse traps.
Guess you've never seen the mess you get by mixing antifreeze types that aren't compatible. Honda blue with regular green equals gel. Volkswagen mixed with Hyundai equals slime. Incompatible types can lead to electrolysis and reactions with gasket materials, engine components and just isn't worth the risk. There's no telling what the red stuff might be. We have 3 types in the brand I work on. Pink, green and low conductivity blue for ev cooling systems. Absolutely no mixing allowed!
