Are you sure the clear patch an colorize when it's in a later stage than previous renderers? By default, it renders with an alpha of 0% (completely transparent), and yet dragging one into a working composition will make it black. By your definition, it should do nothing to the visual output. Modifying the alpha to 10% keeps it black too.
I believe the clear patch only employs the glClear function, which doesn't operate on existing pixels -- it just ignores them and overwrites them with a constant color. Thus, alpha blending (as suggested) isn't possible.
Damn, you're right! I could have sworn that was how I did fades previously though. Maybe it was a different patch? It definitely used a color mixer + opacity though.
I'll remove that from the wiki page and check out how I did it before.
