I am trying to do some colour transformations with Fx function, but is doesn't work.

If I use
There is probably some fundamental mistake in my expression, but I can't see it. Can anybody give me an advice?
If I use this expression inside Fx function
"rgb((1-u.r)*255,128,128)"the result is black image. The actual transformation is more complicated, but I can't get even this simple one to work.
If I use
"rgb(0,128,128)"the result is plain colour image as expected.
