make alpha spite white?

[destro]

Is it possible to make sprite with alpha more white, maybe not 100% white but whiter than orginal, would be great if color of sprite works like that black to 50%grey like multiplay and from grey to white like screen in photoshop for now I only need whitefuncionality but more flexible way to control spites color can be always usefull

You can do anything you like in a shader. Remember though that changing the shader will affect performance, especially if its something more "complicated" like what you're requesting. I don't think screen is possible with blend hardware.
