I am pretty sure that it will require quite a bit of doing. Not from experience, as I only use super dri, and get tons of white smoke from my Brison. I have been told that since the smoke is simply smoldering fuel (for lack of a better description) thus coloring the fluid would do nothing. The only answer that seemed practical for model use was to get the colored smoke generators, although you will be limited to lighting them and not being able to turn the smoke on and off. I might be wrong, but from other forums I seem to remeber that this was the only was to do it. Hope other chime in as this would be of interest to me as well.
