Okay you people with big brains please apply any spare cranial capacity to
my problem

Brown!

I want a brown media that makes any clear object translucent brown.  I've
pulled loads of hair out and the nearest I can get is green.. After fiddling
for hours I ended with this rubbish below.  I just want it to look brown.

Where do I start!

                                media   {
                                        emission color <0.25, 0.15, 0.05>
                                               }

Yeesh, do something to the indentation...
You want translucent brown. That code will produce media that glows a 
dull orangish red. Dark orange and brown are pretty much the same thing, 
but your brain will refuse to see a glowing object as brown.
For this, you want either interior attenuation or absorbing media. For 
example:

sphere {< 0, 2, 0>, 2 hollow
    texture {pigment {color rgbf 1}}
    interior {
        ior 1.33
        media {absorption < 0.7, 0.8, 0.98>}
    }
}

sphere {< 0, 2, 0>, 2
    texture {pigment {color rgbf 1}}
    interior {
        ior 1.33
        fade_power 1000
        fade_distance 1
        fade_color <0.3, 0.2, 0.02>
    }
}
