In addition to the different patterns of plastic bags, what can highlight the theme is the transmission of color. Today, let's talk about the color design of shopping bags

1、色彩的冷暧感

1. The cool and warm feeling of color

比如取暖器这种给人温暖的东西我们通常会用红、橙、黄这种暖色系来表达。饮料或啤酒通常用青、蓝能让人产生清凉感的冷色系表达

For example, we usually use the warm colors of red, orange and yellow to express the warm things. Drinks or beer are usually expressed in a cool blue or blue color system

2、色彩的层次感

2. The layered sense of color

  图案中的场景除了色彩分明外还要有层次感，比如从远景到近景，从大到小，从模糊到清晰，颜色深浅引起强烈的视觉反差来衬托主题，更能够让人仿服置身于场景中

In addition to clear colors, the scene in the pattern should also have a sense of hierarchy. For example, from the perspective to the close range, from large to small, from fuzzy to clear, the color depth causes a strong visual contrast to set off the theme, which can make people imitate and put themselves in the scene

3、色彩的明暗度

3. The lightness of color

   饱和度不同表达的意思不同，明度高的浅色和色相偏冷的色彩感觉较轻，其中白色更轻；明度低的深暗色彩和色相偏暖的色彩感觉重，其中黑色更重。明度相同、纯度高的色彩感觉较轻，而冷色又比暖色显得轻。

Different saturations have different meanings. Light colors with high lightness and cool hues feel lighter, among which white is the lightest; dark colors with low lightness and warm hues feel heavier, among which black is the most important. The color with the same lightness and high purity feels lighter, while the cool color is lighter than the warm color.

4、色彩的味觉感

4. Taste of color

一般红、黄、白色会让人感受到甜味；绿色会有酸味；黑色会有苦味；白、青色会有咸味；黄、米黄会有奶香味。所以不同口味的食品运用的色彩不同，色彩用的好更能激起消费者的购买欲望，达到更好的效果

Generally, red, yellow and white will make people feel sweet; green will have sour taste; black will have bitter taste; white and cyan will have salty taste; yellow and Beige will have milk flavor. Therefore, different flavors of food use different colors, good color can arouse the desire of consumers to buy, to achieve better results

5、色彩的华丽感

5. The gorgeous feeling of color

在包装上需要色彩来表达一件商品的价值，纯度和明度较高的鲜明色，如红、橙、黄等具有较强的华贵感，而纯度和明度较低的沉着色，如蓝、绿等显得质朴素雅

Color is needed to express the value of a commodity on the package. Bright colors with higher purity and lightness, such as red, orange and yellow, have a strong sense of luxury, while dark colors with low purity and lightness, such as blue and green, appear simple and elegant
