I would say that I am not aware of any rules about when to wear or when not to wear red. As someone else stated, red is usually worn around Valentines Day, a lot of people wear red around Christmas time.
Sometimes women dress in red to commemorate the American Heart Association's group called Go Red for Women. It symbolizes heart disease awareness and promotes heart health awareness in women. Heart disease is the leading cause of death in women.
Red is also the color of love so many times women will dress in red when they are trying to appear sensual or sexy, perhaps on a date.
Red is a very strong color and can add confidence when it may be lacking. Wear read to help you feel strong and secure.
If colors affect our moods, and I'm not sure that they always do, they probably don't always affect everyone's moods in the same way. Some people may find red to be sensual and confidence-inspiring, as does the previous poster, but others may perceive red as aggressive or attention-seeking.
The shade of red probably is important, but at least as important is the social setting. When I think of wearing red, as in really red, I would probably limit myself to high-energy social gatherings. I don't think I would wear anything really red in a formal meeting, unless the people around me also wore bright, attention-getting colors.
There's a great image from the film The Matrix that shows the power of the red dress against a backdrop of more muted colors. The cut of the dress here influences our reaction, of course, as does the woman's hairstyle, but overall -- for me, at least -- really red is good for the club or ballroom but bad for the boardroom or classroom.
Point made in post above is understood and accepted. In my post # 5, I was only trying to point out that regional differences may exist.
In reply to post#5, I just can say that the recommendations given are nothing but the result of psychotherapists' research findings in relation to the effects of colors on human behavior and thinking.
Moreover, the post#1 does not indicate that recommendations have to be made in relation to geographical areas or cultural traditions.
Colours are related with mood and atmosphere.
Red is considered as a colour of passion mostly. Its recommended on the days which are related to love. Red rose and red dresses are used in the valentine's day parties. Red rose is gifted to the beloved. In many countries, red dresses are worn by brides on the matrimonial day.
I am not clear who is recommending dressing in red, on what occasion, and who is he person so advised.
As far as my observation red is not a very popular colour for normal dressing. Red colour is reputed to be most easily noticeable by human eye, and therefor people who need to be easily spotted especially in some emergency may wear clothes that are red.
Specific recommendations for the occasion for wearing red colour given in Post #2 appear to be culturally defined. For example, I just cannot imagine too many people in India, wearing a red shirt for an important business meeting.
Red is a color that transmits a feeling of optimism and good vibes. At the same time,red gives a certain aura of sensuality those who wear this color. The persons dressed in red,they will feel better and more confident in their own forces.
You have to dress in red before an exam or an important meeting when you feel like you are tense and afraid not to be wrong.
This color will restore your faith in you and help you not fail.
You also have to dress in red to a meeting where you know you're not appreciated, in an environment less hospitable, because red will give you a feeling of safety and you will be less sensitive to the feelings nurtured and shown by the others.
