Synesthesia.
Someone who has synesthesia sees colours in numbers, letters, sound, or other things. There are many different types. Some people with synesthesia feel sounds, see pictures in names, believe numbers have personality, and many more things. You can take a free synesthesia test on synesthete.org . Something else is that the symptoms never change. say that if somebody smells cherries when they see the number 5. He or she will always smell cherries when they see the number 5 it will never change.

This can be caused by a condition known as Synesthesia. Synesthesia can cross the senses in the brain in a way that makes them connect to each other, even when they shouldn't be connected. Supposedly, the effect can also be caused by hallucinatory drugs. Many people suggest not trying this.
Synesthesia is a comparatively rare phenomena or condition that is reported to occur in 1 in every 500 to 25,000 people. Synesthesia facts suggest that this condition is found more in females as compared to males. The male is to female ratio is said to be at 5:1. The word synesthesia has its roots in Greek literature and means dual or joined senses. Synesthesia facts can tell you that synesthetes may have new approaches to sounds and colors than a normal human being. They may associate color with music and smell with images. There are many proved facts and examples of synesthesia occurrences and scientists are at present engaged to find out more about the condition and how it can be used to solve many mysteries.
Synesthesia is a condition in which the senses mix together (for example some people with Synesthesia see certain colors for certain sounds, or hear different sounds for different colors, and so on. So smells can have colors for someone with Synesthesia. There is no definite answer I can give, for three reasons. One, you did not specify which type of odor in your question. Two, I, nor anyone I know has Synesthesia. Three, the mixing of senses for people with Synesthesia is unique for every person affected, so it is impossible to give a true answer.
1 in 23 people have it. It is common. Unfortunately, the majority of synesthetes (people with synesthesia) don't realize they have it because the symptoms are so minor, they think it happens to everybody, or they just have never heard of it.

Synesthesia can be temporarily lost during stressful situations such as the death of a loved one. Also, sometimes head trauma can cause one to lose synesthesia. It really just depends on your situation. Chances are it'll come back, though. For example, I've known people who have lost their synesthesia when a loved one passed away, and after the intense stress and pain of that situation subsided, their synesthesia returned same as ever.
