Why would the main one read near Min and the others over Max? Engine is cold.

This is normal. The MAX line is a service line for cold. As long as it's above the MIN and close to the MAX line, you'll be fine. With the fluid so close to the MAX line, you have nothing to worry about. It's not that sensitive where you're going to hurt anything. Service everything to the MAX line cold and you'll be fine. (You're perfectly fine as it sits right now, as well.)

The real question is, if they’re the same coolant, why are they different colors?

I prefer the Grape flavor. Lol

The factory stuff is Strawberry.
I bought a Pacifica hybrid and it has 3 separate coolant systems and every one of them is a different color. They of course use the same as our Jeeps, some blend of purple/pink.

Mine is a 2020 2.0t JLU Sport also has a black tank. This is the most annoying design ever. You have to unscrew the cap and use the dipstick built into the cap to check level. I seem to need to top off with about half a cup of coolant a month but cannot find a leak. Not sure if this is a problem or not. Is this amount of coolant loss OK?

My understanding was that the same coolant was supposed to be used in both the black (rear) coolant tank and the opaque (front) coolant tank. Are people using different coolant in different tanks or are the different colors coming from switching coolant brand and filling up/topping off with different color coolant?
