代码：

![复制代码][20181224070734617]

plt.subplots(1, 1)
    x= range(100)
    y= [i**2 for i in x]
    
    plt.plot(x, y, linewidth = '1', label = "test", color=' coral ', linestyle=':', marker='|')
    plt.legend(loc='upper left')
    plt.show()

结果：

![20181224070734804][]

说明：其实上面color=' coral '中，可以换成color=' \#054E9F'，每两个十六进制数分别代表R、G、B分量：

上面对应的颜色：

另外的显示方式：

装了seaborn扩展的话，在字典seaborn.xkcd\_rgb中包含所有的xkcd crowdsourced color names。如下：

plt.plot([1,2], lw=4, c=seaborn.xkcd_rgb['baby poop green'])

所有颜色如下：
