Brown silicon is an allotrope of metallic (grey) silicon.
"Red silicon" isn't an allotrope because it isn't just elemental silicon - it's a silicon-containing plastic (a silicone).

For it to be an allotrope the atoms would have to be bonded in a different way. Silicon only bonds in a tetrahedral structure where each silicon is bonded to four others and is dark grey in colour. Red and brown silicon are probably just compounds where the other constituents give the different colours.

they are not classified as allotopes of phosphorus because they both exhibit the samediamond-like structure
