Our smoke systems are designed to comply with FAR/AIM §137.37 - “No persons may dispense, or cause to be dispensed, from an aircraft, any material or substance in a manner that creates a hazard to persons or property on the surface”. Colored smoke can stain or damage aircraft paint and also risks of staining spectators or property on the ground if deployed at lower altitudes.

For these reasons colored smoke is not approved for use in Smoking Airplanes systems.
