no it doesnt matter
there r alot of different colored buds out there
purple
blue
of course green
brown
golden
and white
i believe different colored buds can b from different types of climates
and the nutreints in the soil has some 2 do with it also
if u have brown bud
and u r getting hi
go with it

i do remember years ago
when u could get columbian gold(really a golden brown)
or the brown tye sticks(brown)
kicked ur ass 4 sure
