Try this two-steps approach:
1. Select all blue/black polygons B which are in large green polygon A using Select By Location from Selection menu.
2. Use Summary Statistics tool (Analysis->Statistics->Summary Statistics) to calculate summary area for each type of polygon B with settings:
- Statistics Field: Shape_Area
- Statistics Type: SUM
- Case field: type field - the field based on which you differentiate polygons color.

I just used as type field my "capture date" and in fact, that the format is sometimes dd.mm.yy and sometimes with dd.mm.yy + time I got seperated values. Can i drop the time before in my attribute column?
To drop the time: create new column and use this simple expression in Field Calculator with Python parser:
(which takes only first 10 characters)
