instead of connecting the 4th outlet of [part_info] directly to [color],
use it to trigger the generation of 3 random values, and feed those to
[color].

if you want the colors to be persistent (that is: a given particle will
have the _same_ random colors in 2 consecutive render cycles), you might
want to reset the random generator to a given "seed" for each render cycle.
a good time and place to do that would be the bang from a [t a b] right
before [part_info].

more interesting things could be acchieved by storing the "random"
values in a table (of size partnum) and read those values, starting at 0
for each render cycle (again: derived from the trigger [part_info]
receives) and incrementing the counter for each particle (derived from
the output of [part_info].
