1、颜色是通过眼、脑和我们的生活经验所产生的一种对光的视觉效应。人对颜色的感觉不仅仅由光的物理性质所决定，比如人类对颜色的感觉往往受到周围颜色的影响。有时人们也将物质产生不同颜色的物理特性直接称为颜色。

Color is a visual effect on light produced by the eyes, brain and our life experience. Human perception of color is not only determined by the physical properties of light. For example, human perception of color is often affected by surrounding colors. Sometimes people call the physical properties of substances that produce different colors directly as colors.

2、颜色心理效应

（1）红色

视觉震撼力强，让人觉得活跃、热烈、轰轰烈烈、有朝气。在人们的观念中，红色往往与吉祥、好运、喜庆相联系，它便自然成为一种节日、庆祝活动的常用色。同时红色又易联想到血液和火炮，有一种生命感、跳动感，还有危险、恐怖的血腥气味的联想。灭火器、消防车都是红颜色的。

Red

The visual shock is strong, making people feel active, enthusiastic, vigorous and energetic. In peoples concept, red is often associated with auspiciousness, good luck, and joy, and it naturally becomes a common color in festivals and celebrations. At the same time, red is easily associated with blood and artillery, with a sense of life, beating, and the association of dangerous and terrifying blood. Fire extinguishers and fire trucks are all red.

（2）黄色

温柔和娇美的颜色，有很强的温暖感，使人感到愉悦和纯洁。枯萎的植物往往呈淡黄色，又有衰老、老年、黄昏的联想，还可以让人想起极富营养的蛋黄、奶油及其他食品。但是，黄色又与病弱有关，植物的衰败、枯萎也与黄色相关联。因此，黄色又使人感到空虚、贫乏和不健康。

yellow

Gentle and delicate colors, there is a strong sense of warmth, making people feel happy and pure. Withered plants are often pale yellow, and have the associations of senescence, old age, and dusk, and can also remind people of highly nutritious egg yolks, butter and other foods. However, yellow is related to disease and weakness, and plant decay and withering are also related to yellow. Therefore, yellow makes people feel empty, poor and unhealthy.
