So I bought peak red/pink coolant to top off my vehicles coolant but I noticed it’s actually red as my car has pink. Is this bad to do? I alrdy topped off my car with it. The coolant says it’s compatible and for topping off but the colors are different so I’m worried

Coolant colors. What do they mean?
The pink coolant is an OAT (organic acid technology) that typically has a longer service life. The red coolant is just an "Extended Life" OAT (organic acid technology) HOAT
You're fine mixing OAT with HOAT.
You should NEVER mix OAT based formulas (which includes hoat) with IAT formulas.
