So im trying to make instead of the flame or other particles, having the particle be a black colored dust particle. Can i get help on what to change in this?
I've tried these:

   if name of player's tool is "particles":
      draw 25 of dust using dustOption(rgb(100, 100, 100), 1) at location(21.5, -58, 239.5, world)
      set {_shapes::circle} to a circle with radius 1.5
      set {_c} to dustOption(red, 1)
      set particle of {_shapes::*} to falling lava
      draw shapes {_shapes::*} at location(21.5, -58, 239.5, world)

on right click:
   if name of player's tool is "particles":
      set {_shapes::circle} to a circle with radius 1.5
      set {_c} to dustOption(red, 1)
      set particle of {_shapes::*} to {_c}
      draw shapes {_shapes::*} at location(21.5, -58, 239.5, world)```
