In the pyrotechnic coloured smoke devices dye is also used to add the colour, and these smoke devices also pose a high stain risk. The best advice for producing clean coloured smoke is to colour the smoke with light using beam control to selectively colour smoke in a scene." http://www.bigclive.com/smoke.htm “Experimentation has been done in the past with adding coloured dyes to smoke fluid to produce coloured smoke, however, the amount of dye required is high and the risk of staining is also too high to make the technique worthwhile.

For that effect you'd need to put some kind of solid particles in the air using a smoke machine. @Kyle Hertler: Unfortunately no, you can’t make colored fog.

Although Glycerine is present in loads of cosmetic product, the BBQ foil dish and naked flame candle doesn't cut it. Go eBay buy a mist fogger, cheap. You can power it with laptop adpater DC ~19V to 24V max, oh yes that cost 5 bucks too, free delivery from HK, direct a gentle breeze over the mist, you got your fog.  Not impressed!
