Red shirt colour is associated with long-term team success in English football

Abstract

The colour of sportswear has been shown to influence the outcome of bouts for several different combat sports. The generality of these effects, and whether they extend to collaborative forms of contests (team sports), is uncertain. Since 1947, English football teams wearing red shirts have been champions more often than expected on the basis of the proportion of clubs playing in red. To investigate whether this indicates an enhancement of long-term performance in red-wearing teams, we analysed the relative league positions of teams wearing different hues. Across all league divisions, red teams had the best home record, with significant differences in both percentage of maximum points achieved and mean position in the home league table. The effects were not due simply to a difference between teams playing in a colour and those playing in a predominantly white uniform, as the latter performed better than teams in yellow hues. No significant differences were found for performance in matches away from home, when teams commonly do not wear their “home” colours. A matched-pairs analysis of red and non-red wearing teams in eight English cities shows significantly better performance of red teams over a 55-year period. These effects on long-term success have consequences for colour selection in team sports, confirm that wearing red enhances performance in a variety of competitive contexts, and provide further impetus for studies of the mechanisms underlying these effects.     

浅析《说文解字》中颜色词的特点

《说文解字》作为我国第一部字典,所收录的颜色词具有强烈的时代特色。《说文解字》中的颜色词仍然具有古代的"以物呈色"的特点,无论是单纯词还是表两种及以上颜色的词都在表义上具有其颜色载体的某些特质。在表现多种颜色混在一起的词的时候由原来的简单描绘到灵活指称。在表示色彩时有了明暗度和色彩间度的区别,但所表颜色倾向于深色,总带有脱胎而来的物的相关特点。词量的增加推进了构词手段的发展,空间的名称逐渐被时间的构词顺序取代。系统的变化导致新词的增加,使原来不具有颜色意义的词进入到颜色系当中。     

北京昌平地区京粉翠的宝石学特征及其致色原因

京粉翠具有艳丽高雅的粉桃红色、玫瑰粉红色等喜人的色泽,但是到目前为止对于其致色原因尚不清楚.针对北京市昌平区的4种不同颜色的京粉翠,进行了宝石学常规参数的测定实验,以及对特征矿物进行了电子探针分析.通过宝石学特征发现,京粉翠随着颜色的增加,其折射率略有增加,其密度随着颜色的加深而增加.通过观察不同颜色的京粉翠在偏光显微镜下的特征,发现京粉翠的主要矿物组成为：蔷薇辉石、石英和长石等.通过不同颜色的矿物电子探针的分析,得出京粉翠的致色成因主要由其中Mn元素含量决定,Fe的含量也起一定的影响作用.
