I'm sure I can't be the only one to have thought of this, but I don't feel like scouring the forums to find the answers, so if it has already been answered sorry for bringing it up again, but is there a way to change the color of the vapor on the exhale? I think it would be really cool to exhale a big blue (or green etc...) cloud of smoke. So yeah, any help pointing me in the right direction if it can be done. If not, I;m a sad panda for now...
