这篇文章主要介绍了基于Tkinter利用python实现颜色空间转换程序，感兴趣的小伙伴们可以参考一下

本文主要基于colorsys实现，样例是从hls转换到rgb，如果要换颜色空间很容易只需要修改一个函数，具体内容如下

用到了Scale和Canvas组件。

运行效果图：

python实现颜色空间转换程序(Tkinter)

代码如下：

									from Tkinter import *

									import colorsys 

									#操作后的响应函数 

									def update(* args): 

									  'color'

									  r,g,b = colorsys.hls_to_rgb(h.get() / 255.0, l.get() / 255.0, s.get() / 255.0) 

									  r,g,b = r * 255, g * 255, b * 255

									  rgb.configure(text = 'RGB:(%d, %d, %d)' % (r, g, b)) 

									  c.configure(bg = '#%02X%02X%02X' %(r, g, b)) 

									root = Tk() 

									hue = Label(root, text = 'Hue') 

									hue.grid(row = 0, column = 0) 

									light = Label(root, text = 'Lightness') 

									light.grid(row = 0, column = 1) 

									sat = Label(root, text = 'Saturation') 

									sat.grid(row = 0, column = 2) 

									#初始化颜色为rgb的000，也就是纯黑色 

									rgb = Label(root, text = 'RGB(0, 0, 0)') 

									rgb.grid(row = 0, column = 3) 

									h = Scale(root, from_ = 255, to = 0, command = update) 

									h.grid(row = 1, column = 0) 

									l = Scale(root, from_ = 255, to = 0, command = update) 

									l.grid(row = 1, column = 1) 

									s = Scale(root, from_ = 255, to = 0, command = update) 

									s.grid(row = 1, column = 2) 

									c = Canvas(root, width = 100, height = 100, bg = 'Black') 

									c.grid(row = 1, column = 3) 

									root.mainloop()
