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。

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()
