the problem you face is that these two functions are actually doing the 
exact same thing. when passing color values to the Font.render method, 
they ignore the alpha value. if you pass any background color, it will 
return an image with solid alpha. if you pass no argument for the 
background color, then you will get a rendered image with proper alpha.

for the first version of your function you will want to call it like this

rendered_surf = f.render("blah blah", 1, (255,255,255))

that should give you the type of image you are looking for.
