python 简单的颜色序列生成器

2021/04/21：我火星了？？？？

python Seaborn库调色板

所以下面的东西都别看了

.

由来

昨天画了这张图，自动分配的颜色比较深，而且总颜色数不多，这张图的颜色是自己一点一点写的，很麻烦，所以想制作一个简单的颜色序列生成器一劳永逸

介绍

我给这个文件取名为InterestingColorfulColor.py，把它放在python安装目录的Lib文件夹就可以随时用import语句导入，非常方便。
例如：

import InterestingColorfulColor as ICC

目前这个文件的主要内容只有一个类：ColorOrder
ColorOrder类里给出了15种按照颜色深浅梯度变化的基础颜色序列，分别为：红，红橙，橙，橙黄，黄，黄绿，绿，绿青，青，青蓝，蓝，蓝紫，紫，紫红，和灰色（由纯黑到纯白）
每种序列有16种不同的颜色。
通过这个类可以较为轻松地得到一种你想要的颜色序列，有可能可以让你的工作提高一点点效率。不过这毕竟是个小制作，功能不复杂。
下图展示其中一部分颜色

使用

约定

约定上述15种颜色序列为 gray red, orange,yellow,green,cyan,blue,purple 以及除了gray外剩下七种颜色中相邻颜色之间的两两组合如redorange, greencyan等，对两种颜色书写的先后顺序不做要求即redpurple和purplered都是正确的

导入模块

import InterestingColorfulColor as ICC

创建一个ColorOrder对象

co = ICC.ColorOrder(['red','blue'],mixtype = 'cross')

参数解析：
def init(self, colornames, mixtype = ‘Connect’)
两个参数，colornames ， mixtype

参数colornamse给出若干个颜色序列的名称。
参数mixtype表示混合这些颜色序列的方式，目前只有两个值：connect 和 cross（不需要区分大小写）
connect为默认值以连接的方式混合，即按照顺序依次把colornames中给出的颜色序列首尾相接
cross 以交叉的方式混合。举个例子如果以cross的方式混合三个颜色序列[1,2,3][a,b,c][x,y,z] 最后的结果序列为[1,a,x,2,b,y,3,c,z]

查看颜色序列，以及其他两个隐藏属性

co.getOrder() #查看序列
co.getLength() #查看序列长度
co.getBaseOrderNumber() #查看该序列由几个基础序列混合而成结果：
['#2F0000', '#000079', '#4D0000', '#000093', '#600000', '#0000C6', '#750000', '#0000C6', '#930000', '#0000E3', '#AE0000', '#2828FF', '#CE0000', '#4A4AFF', '#EA0000', '#6A6AFF', '#FF0000', '#7D7DFF', '#FF2D2D', '#9393FF', '#FF5151', '#AAAAFF', '#ff7575', '#B9B9FF', '#FF9797', '#CECEFF', '#FFB5B5', '#DDDDFF', '#FFD2D2', '#ECECFF', '#FFECEC','#FBFBFF']
32
2

切片获取序列

co.getLeft(False) #获得序列左边的25%
co.getRight(True) #获得序列右边的25%
co.getMiddle() #获得序列中间的50%

参数分析：
def getLeft(self, muti_section = False):
三个方法只有一个相同的参数，muti_section
当muti_section默认为False 直接根据需求获得序列的前25%或后25%或中间50%
当muti_section为True，考虑某些时候切片以connect方式混合的序列，他会单独提取每个基础序列的左、右或中间的部分，拼接到一起作为返回结果

与ColorOrder对象的序列混合

co.mix(co,'cross')

参数解析：
def mix(self, co, mixtype = ‘Connect’)
co为实例对象，mixtype与__init__中的mixtype相同
值得一提的是这时两个序列不一定时等长的，我们再举一个cross混合的例子。假设混合[2,3,4,2,3,4,2,3,4]和[0,1,0,1,0,1]两个序列，最后的结果是[2,3,4,0,1,2,3,4,0,1,2,3,4,0 1]

应用简例

%matplotlib inline
import InterestingColorfulColor as ICC
import matplotlib.pyplot as pltfig, ax = plt.subplots(1,2,figsize = (16,8))co = ICC.ColorOrder(['blue','redpurple'],'cross')
ax[0].pie([1]*len(co.getOrder()),colors = co.getOrder())co.mix(ICC.ColorOrder(['Green']),'cross')
ax[1].pie([1]*len(co.getMiddle()),colors = co.getMiddle())

效果：

%……&%￥……？？？？？！！！

弄到颜色序列之后是可以用co.getOrder()导出来自己随便切的，并不是只能按照getMiddle,getLeft,getRight的固定方式切片
