The combination of color area and visual effect of packaging design

　　The occupancy and reasonable configuration of color area is quite important in color composition. As the size of the color area increases or decreases, the amount of color, etc. will also increase or decrease, the visual stimulation and psychological impact will also increase or decrease.
　　For example: 1 c ㎡ of black appears in the visual range, will give a clear and clean visual effect, in front of 1 ㎡ of black will produce a serious, dull psychological feeling, and when people are in 100 ㎡ of black surrounded by a negative feeling, and then produce a gloomy psychological reflection. Another example is 1c ㎡ of solid color big red, so that people feel bright and lovely, 1 ㎡ of solid color big red, so that people feel excited and excited, when people are in 100 ㎡ of solid color big red surrounded, there will be over-stimulated and caused by the feeling of fatigue. And then produce a kind of unbearable kind of trouble.
　　Usually large areas of color design more than choose high brightness, low color, contrast weak color, to bring bright, lasting and harmonious comfort, such as: buildings, indoor ceilings, walls, booths.
　　Medium area of the color more with a medium degree of contrast, such as: clothing color matching, neighboring color groups and brightness of the medium tone contrast is used more, both to arouse visual interest, but not excessive stimulation. Small areas of color commonly used bright colors and bright colors and strong contrast, such as small goods, small signs, etc., the purpose is to make people fully attention.
　　Shape is one of the figurative elements of color presence. The appearance of a color is always accompanied by a certain shape that we feel at the same time.
　　The shape is gradually divided from concentrated to dispersed, and although the total amount of color in the picture remains unchanged, the effect of contrast is greatly changed.
　　In the composition design, the different positions occupied by the color images bring considerable influence to the visual effect of the picture. The process of design is actually a process of arranging and adjusting the position of the image, using the changes in the position of the image, can be designed to create different picture effects.
　　1, red and green colors away from each other, the contrast effect is weak.
　　2, the red and green colors are adjacent to each other, the contrast effect is slightly stronger.
　　3, red and green colors are surrounded and surrounded by the state, the contrast effect is enhanced.
　　4, red in the green completely surrounded, as the base color of gray does not play a role in the transition, the contrast effect is the strongest.
