Welcome to the community!
AS for yyour question, the revered Ken seems to have answered it, and I'll only add a
little notation that I prefer..

when you do :
cylinder {
  <-5,0,0>,<5,0,0>,1
  pigment {
    gradient x
    colour_map {
      [0 rgbf <1, 0.8, 0.8, 0> ]
      [1 rgbf <1, 1, 1, 1> ]
    }
  }
}
You'll see it changes very quickly, and that th transparent part isn't exactly as good
as
you may like it(I usually want big areas transparent, and a smaller passing.)
Then this may be better :
cylinder {
  <-5,0,0>,<5,0,0>,1
  pigment {
    gradient x
    colour_map {
      [0/5 rgbf <1, 0.8, 0.8, 0> ]
      [2/5 rgbf <1, 0.8, 0.8, 0> ]
      [3/5 rgbf <1, 1, 1, 1> ]
      [5/5 rgbf <1, 1, 1, 1> ]
    }
  }
}

This will make a smooth passing, and still leave parts of the cylinder in solid
colour.
(oh, add this, for example. : turbulence <1.8,1.3,0.1> octaves 10 lambda 1.2 omega
1/14 )
