When using a vapor smart barrier, should vapor open paint be used? – GreenBuildingAdvisor

We are building a house in Wisconsin and went with Intello for our air barrier. What we are now trying to determine is whether we should use a specialty paint like Keim Mineral Primer and Keim Innostar paint that is made to be highly vapor permeable and mold and fungi resistant. My thoughts are wouldn’t a normal latex paint somewhat defeat the purpose of the Intello?
And, if it’s worth it to use a product like Keim throughout the home, would doing something less permeable in the bathrooms (something like a regular latex in eggshell) be a good idea since they tend to be more humid areas?
