1、顏色是通過眼、腦和我們的生活經驗所產生的一種對光的視覺效應。人對顏色的感覺不僅僅由光的物理性質所決定，比如人類對顏色的感覺往往受到周圍顏色的影響。有時人們也將物質產生不同顏色的物理特性直接稱為顏色。
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、顏色心理效應
（1）紅色
視覺震撼力強，讓人覺得活躍、熱烈、轟轟烈烈、有朝氣。在人們的觀念中，紅色往往與吉祥、好運、喜慶相聯繫，它便自然成為一種節日、慶祝活動的常用色。同時紅色又易聯想到血液和火炮，有一種生命感、跳動感，還有危險、恐怖的血腥氣味的聯想。滅火器、消防車都是紅顏色的。
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）黃色
温柔和嬌美的顏色，有很強的温暖感，使人感到愉悦和純潔。枯萎的植物往往呈淡黃色，又有衰老、老年、黃昏的聯想，還可以讓人想起極富營養的蛋黃、奶油及其他食品。但是，黃色又與病弱有關，植物的衰敗、枯萎也與黃色相關聯。因此，黃色又使人感到空虛、貧乏和不健康。
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.
