Smell or the olfactory perception of the gases or compounds that surround us is an indication that man uses to perceive a lot of things. The freshness, staleness, dirt and cleanness are things that we perceive with our eyes closed.

Scientists say that white smell, like white sound is a combination of smells. It can only be conjured in a laboratory. When the components of the compounds projected themselves, we perceive the smell.

Many wavelengths are mixed to produce the white light and scientists conducted a similar experiment with smell. However, human olfactory experiments were a failure seemingly because they failed to react properly to mixtures that had more components.

White smell is entirely bland and so it is very difficult to describe it properly.
