On the page:

http://wiki.povray.org/content?title=Reference:Color_Expressions

wondering about the brackets around rgbft? I think there is no reason 
for them.

COLOR_VECTOR:
     rgb <3_Term_Vector>    |
     rgbf <4_Term_Vector>   |
     rgbt <4_Term_Vector>   |
     [ rgbft ] <5_Term_Vector> |
     srgb <3_Term_Vector>   |
     srgbf <4_Term_Vector>  |
     srgbt <4_Term_Vector>  |
     srgbft <5_Term_Vector>
