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、色彩的冷曖感

1. The cool and warm feeling of color

比如取暖器這種給人溫暖的東西我們通常會用紅、橙、黃這種暖色系來表達。飲料或啤酒通常用青、藍能讓人產生清涼感的冷色系表達

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、色彩的層次感

2. The layered sense of color

  圖案中的場景除了色彩分明外還要有層次感，比如從遠景到近景，從大到小，從模糊到清晰，顏色深淺引起強烈的視覺反差來襯托主題，更能夠讓人仿服置身于場景中

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

   飽和度不同表達的意思不同，明度高的淺色和色相偏冷的色彩感覺較輕，其中白色更輕；明度低的深暗色彩和色相偏暖的色彩感覺重，其中黑色更重。明度相同、純度高的色彩感覺較輕，而冷色又比暖色顯得輕。

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、色彩的味覺感

4. Taste of color

一般紅、黃、白色會讓人感受到甜味；綠色會有酸味；黑色會有苦味；白、青色會有咸味；黃、米黃會有奶香味。所以不同口味的食品運用的色彩不同，色彩用的好更能激起消費者的購買欲望，達到更好的效果

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、色彩的華麗感

5. The gorgeous feeling of color

在包裝上需要色彩來表達一件商品的價值，純度和明度較高的鮮明色，如紅、橙、黃等具有較強的華貴感，而純度和明度較低的沉著色，如藍、綠等顯得質樸素雅

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
