You are so clever Ive!  I've been struggling using the peeron "official colors"
and being so light.  Wow, what a difference!  Sadly, I'll having to render all
my scenes again. :(

I may try your finish.  Here's what I've been using:

// brick finish
#declare lf_brick = finish {
    #if (l_ambient) // normal
      diffuse 0.5
      ambient 0.3
    #else           // radiosity
      diffuse 0.8
      ambient 0
    #end
    phong 0.6 phong_size 40
    specular .1
    #if (l_shiny)   // reflection on
        reflection { 0,.05 falloff .5}
        conserve_energy
    #end
}

Thanks for sharing!!!
