During the time i drove a cab, a person once asked me where i learnt to drive (implying i'm a rough driver). To that i said to him "Where i come from Red means go. Green means go. And Yellow means.. oh what the **, GO!"
:D
I've seen, some where on TV or in real life maybe .. there are some places with just red and green lights .. no yellow .. I cant remember where...
But is not that funny ..
Colors do pass message but the way we recieve the message depends upon our norms and culture
There was a time when in fashion industry .. mixing brown and black .. or green and blue was a crime ...
and it used to seem odd when you see someone wearing brown shirt on black pants ..
Here are some different views on some colors taken from an article on the Internet:
Green
Life and Renewal: Green is life. Abundant in nature, green signifies growth, renewal, health, and environment. On the flip side, green is jealousy or envy (green-eyed monster) and inexperience.
Blue
Calm and Cool : Blue is calming. It can be strong and steadfast or light and friendly. Almost everyone likes some shade of the color blue.
Red
Love and War: Red is hot. It's a strong color that conjures up a range of seemingly conflicting emotions from passionate love to violence and warfare. Red is Cupid and the Devil.
Orange
Flamboyant and Energetic : Orange is vibrant. It's a combination of red and yellow so it shares some common attributes with those colors. It denotes energy, warmth, and the sun. But orange has a bit less intensity or aggression than red, calmed by the cheerfulness of yellow.
