What is the difference between the faded D and the black D on Kik?

So I texted my friend and then it says D and it is the black D. He doesn't have an iphone, i think he has an andriod. What does it mean if it says D which is black? I feel like he is ignoring my text because its been a half an hour and it just says a black D.

The faded D means he is not connected or he has deleted the app. It means he is disconnected. The black D means that the kik has been delivered. Basically the black D is delivered and the faded D is sent but not delivered.
