android black color at 85% opacity

Question

What is the color code of black with 85% opacity?

I have #65000000 - but its too light. I need it a bit darker, at 85% opacity. How do I get that?

And why can\'t

Answer 1

Each component goes from 0 through 255, so 85% opacity would be 85% of 255, i.e. 216.

So: #D8000000
