Color vs B&W

[Yamanipanuchi]

I'm curios on everyone's thought and factual data?

Color...
Pro :
Easier to Identify specific objects

Con:
Harder to analyze (Looking for facts on this).
Larger stored image size

B&W
Pro:
Easier to analyze (Looking for fact on this like above)
Smaller stored image size

Con:
Less information to identify objects
