adding black to blue channel

Hi,
I read that the blue colour in a blue sky can be made a deeper shade of blue by "adding black to the blue channel".
Does anyone know how I can do that?
Thanks,

You can use the RGB balance or perhaps better, the Gamma correction by channel (with the last version)

Hi Antonio,
Alright, I've upgraded to the latest version. What do you mean by "Gamma correction by channel"?
Thanks,
