Woodwind diagrams half hole black white?

[darkijah]

I can find a Black Grey and a Grey White - but I cannot seem to find a 
black white that fits with the rest of the black notes?

I am using the Flute diagram, can someone help me, is it not there or am 
I just blind?

Thanks in advance

Dearly regards
