Some OEM and special types use the other colors. As it is in an atv it might be high aluminum content antifreeze, had to use that stuff in mine.

There are charts you could find online, tell you what vehicles tend to use which coolants, and what all the different colors signify.

There is no general industry specification other than Vehicles use yellow or green and that non-toxic RV is pink or red. Additives can be any color (redline is flourecent pink/orangeish), as can the cooling oil stuff.

kind of guessing the EPA and FDA/DEA defined those colors so they could identify spills and poisonings.

I know once upon a time the two different types were different colors to try and prevent people mixing them together.

European and Japanese spec do have assigned colors I belive.

It is pretty common to see blue windshield fluid these days, maybe too many people were mixing up windshield fluid with antifreeze?

Attached one of those charts for reference

Hahahaha, I just usually buy it from my petroleum supplier when I buy oil and hydraulic fluid. Usually some type of fleet stuff is around.

When buying something I need to trust, sure not buying it from Wallmart, it's not a toaster. View attachment 720323
Walmart sells name brand coolant. They also have super-tec store branded fluids that are highly rated.

I only trust a refractometer anymore,not those hydrometers.
For the Kubota's I mix green coolant 50/50 with distilled water.
I got my refractometer today. That is cool and a great way to check temp and amount of water mixed. I opted for one that cost a little more. But is reads in F not C. REALLY well built. I think I will be a lifetime tool if kept clean.
Thanks.

And you can use it for important things like checking the brix of your grapes... :)

Dam, I just realize that the one I got only has C. Oh well, guess I'll need to convert.

.... in this case is it really that important? water freezes at 0C and -30F and -30C are roughly the same.
