I was how is it possible in inkscape to change the modes of gradients and layers like in this tutorial. http://www.ndesign-studio.com/resources/tutorials/abstract-background/

I think you could easily achieve the same effect that in the first part of this tutorial with gradients from a solid color to full transparency (the default mode in Inkscape by the way). The screen blending mode essentially make the black transparent from what I can see there. As with the blend function presented in the second part of the tutorial, try playing with Effect > Generate from Path > Interpolate.
