课外资料：
1. 红色代表热情、活泼、热闹、温暖、幸福、吉祥 具体指血液（blood）、夕阳、心脏、火焰，抽象—热情、危险、喜庆、反抗、爆发.在中国是吉利，在西方人心目中是奔腾在人体内的"生命之液"。一旦鲜血流淌下 来，生命之花也就凋谢。所以red使西方人联想到"暴力"和"危险"产生了一种颜色禁忌。2. 白色代表纯洁、纯真、朴素、神圣、明快. 具体—白雪、白纸、白云、护士，抽象指纯洁、朴素、神圣、虔诚、虚无.白色在中国文化中，白色与红色相反，是一个基本禁忌词，体现了中国人在物质和精神上的摈弃和厌恶，西方人认为白色高雅纯洁，所以它是西方文化中的崇尚色。它象征纯真无邪，如（1）a white soul纯洁的心灵 3. 紫色代表优雅、高贵、魅力、自傲. 紫色作为祥瑞、高贵的象征，更多地被封建帝王和道教所采用4. 黄色代表明朗、愉快、高贵、希望抽象—明快、注意、光明、不安、野心黄色象征中央政权、国土之义，所以黄色便为历代封建帝王所专有。.5. 蓝色代表深远、永恒、沉静、理智、诚实、寒冷6. 绿色代表新鲜、平静、和平、柔和、安逸、青春，和平、理想、希望、成长、安全.

begin/start-----be on
