Gentlemen, I have discovered that nowhere in the identify -verbose
output is a tally kept of these items (separate colors, I believe):
$ identify -verbose bla.png|grep ') #'|head -2
     11390: (  0,  0,  0,255) #00000000 none
       152: (102,  0,204,  0) #6600CC rgb(102,0,204)

If one wants to know how many there are, one must count them oneself:
$ identify -verbose bla.png|grep -c ') #'
106
