Aggregating conditional distinct counts

    I think logic like the following should work

    All Channels Count = 
// get the list of customers and count the distinct channels for each customer
var CustChannels =  summarize('Table', 'Table'[CustomerName], "ChannelCount", DISTINCTCOUNT( 'Table'[Channel]))
// get the total distinc channels regardless of the filter context
var distinctChannels =COUNTROWS(DISTINCT(ALL('Table'[Channel])))
// count the customers where the number of channels is the same as to the total distinct channels
return countrows(Filter(CustChannels, [ChannelCount] = distinctChannels))

     

    This is giving me the output on the last column

I have a similar challenge:

 

Trying to count unique names (same people repeatedly occur in table rows) in a table based on some other column's categorical status:

 

Homer

Marge

Maggie

Bart
Maggie 

Maggie

Bart

 

They all have a categorical status of "Red, Blue, or Green"  and I wanted to count each employee only once, that hs "red" status.      Can't seem to find the DAX expression for this, or steps to create columns or measures to do this.  

Thanks
