色的轻重则由明度来决定，色彩的纯度起不到什么作用。色彩的软硬感取决于色彩的纯度

无色系的黑、白、灰，整体倾向于寒冷。亮度几乎对寒冷的表现没有影响，颜色的重量由亮度决定，颜色的纯度没有任何作用。色的软硬感取决于色纯度。中纯度的色较为轻柔，而纯度高或纯度低则有强硬感的倾向。颜色本身表明，除了寒冷和温暖之外，还有硬软、强弱、明亮和黑暗、热情和冷静、兴奋或平静、美丽或简单。更重要的是，颜色也刺激人们的感觉系统，影响人们对冷温的判断。举个例子，冬天在寒风中，你会觉得手里的红色手套特别温暖……

科学家们通过人体脑波随着颜色的视觉而变化的实验，发现脑波对红色的反应是警告，放松蓝色。蓝色和绿色是大自然赋予人类的最佳心理镇静剂。人都有这样的体会，当心情烦躁不安时，到公园或海边看看，心情会很快恢复平静，这正是蓝色和绿色对心理调节的结果。这些色调还有助于降低皮肤温度、降低脉搏次数、降低血压、减轻心脏负担等作用。

适当接触这两种颜色有调节神经、镇静、消除疲劳的作用

身心疲劳、压力、精神紧张时，适当接触这两种颜色有调节神经、镇静、消除疲劳的作用。特别是自然绿色对头晕、疲劳、恶心和消极情绪有一定的作用。但是，也要注意适度，长时间在绿色环境中感到冷却，有可能影响胃液的分泌，减少食欲。

蓝色象征着高科技稳定、理性

说了这么多话，现在具体总结一下

红色联想玫瑰，联想到喜庆，联想到兴奋。白色联想到纯洁、清洁、简洁的紫色象征着女性化、高雅、浪漫的蓝色象征着高科技、稳定、理性的橙色代表欢乐、甜美、收获的绿色代表着青春的活力、舒适、希望等。
