Well I noticed that my coolant was low so I grabbed my jug and started topping it off. It took more than I expected but when it came to the top I realized that I was adding purple to my previous green antifreeze. Should I drain and flush it?

Some of the new stuff will mix. What does your purple jug say, your green should be ethylene glycol base.
I can’t even imagine what color that makes

The purple one is ethylene glycol as the main ingredient and when I checked the coolant today it showed up green with no other residue.
Green Bean
SILVER Star
Unless there is a compelling reason, I sure would hate to drain it. The price of coolant has gotten ridiculously expensive. I recently purchased 5 gallons of the Zerex prediluted red flavor and was shocked at the price.

That's why I am asking. The pure green when I popped the cap was encouraging
Why seek speculation? Go to the website of the OEM for the purple stuff and see if they claim it's compatible.
Example This purple mixes with purple, gold and pink
