Please, only british academic english. People can see almost all range colors. And they use their opportunity everywhere where can. For example people use different colours in the road it is traffic light for traffic control. Also for advertising and marketing. Every country have your flag, every flag have your color or a few colors. And if you want know what it is country you can just look in your flag. For example Russia have three colors in your flag - it is white, blue and red. People have association with colors too. Red associated with blood, wine and fire. Write associated with clouds, moral clarity, air. Black associated with disease, war, mystery etc. In conclusion I can say that colours very important for animals, birds and people. That every day we encounter with a few colors and a hundreds shades. Without colours our life will boring.
