I did the port to Lazarus. But no - none of them supports an alpha 
channel, they focus on color selection based on a variety of color 
models. Maybe you should have a look at BGRABitmap and associated controls.

Looking at the demo of the mbColorLib again after some time I see now a 
terrible flicker on Windows. Ondrej, I fear your change in 
double-buffering killed a majority of third-party components. It may 
take some time until all authors will fix this (and most of them left 
their babies...).
