色的輕重則由明度來決定，色彩的純度起不到什么作用。色彩的軟硬感取決于色彩的純度

無色系的黑、白、灰，整體傾向于寒冷。亮度幾乎對寒冷的表現(xiàn)沒有影響，顏色的重量由亮度決定，顏色的純度沒有任何作用。色的軟硬感取決于色純度。中純度的色較為輕柔，而純度高或純度低則有強硬感的傾向。顏色本身表明，除了寒冷和溫暖之外，還有硬軟、強弱、明亮和黑暗、熱情和冷靜、興奮或平靜、美麗或簡單。更重要的是，顏色也刺激人們的感覺系統(tǒng)，影響人們對冷溫的判斷。舉個例子，冬天在寒風中，你會覺得手里的紅色手套特別溫暖……

科學家們通過人體腦波隨著顏色的視覺而變化的實驗，發(fā)現(xiàn)腦波對紅色的反應(yīng)是警告，放松藍色。藍色和綠色是大自然賦予人類的最佳心理鎮(zhèn)靜劑。人都有這樣的體會，當心情煩躁不安時，到公園或海邊看看，心情會很快恢復平靜，這正是藍色和綠色對心理調(diào)節(jié)的結(jié)果。這些色調(diào)還有助于降低皮膚溫度、降低脈搏次數(shù)、降低血壓、減輕心臟負擔等作用。

適當接觸這兩種顏色有調(diào)節(jié)神經(jīng)、鎮(zhèn)靜、消除疲勞的作用

身心疲勞、壓力、精神緊張時，適當接觸這兩種顏色有調(diào)節(jié)神經(jīng)、鎮(zhèn)靜、消除疲勞的作用。特別是自然綠色對頭暈、疲勞、惡心和消極情緒有一定的作用。但是，也要注意適度，長時間在綠色環(huán)境中感到冷卻，有可能影響胃液的分泌，減少食欲。

藍色象征著高科技穩(wěn)定、理性

說了這么多話，現(xiàn)在具體總結(jié)一下

紅色聯(lián)想玫瑰，聯(lián)想到喜慶，聯(lián)想到興奮。白色聯(lián)想到純潔、清潔、簡潔的紫色象征著女性化、高雅、浪漫的藍色象征著高科技、穩(wěn)定、理性的橙色代表歡樂、甜美、收獲的綠色代表著青春的活力、舒適、希望等。
