What does the Green and Yellow building in mission select mean?

[Quink666]

When checking mission in the region screen you can see 2 Building of some kind in the top right. One green and one yellow. Some are crossed out for me so that why im wondering.

It means whether or no you can do co-op in them. If they are both not crossed out, then you can either summon a visitor or do the mission in Yokai Realm. If they are crossed out that means it's a mission you have to do solo. Sometimes there will be missions that have summoning crossed out but it allows you to do Yokai Realm for it anyway.

It means if there's is a shrine and if you can co-op, those without shrines tend to be battles against strong enemies so it's a good way to understand what type of mission it is.
