Default window colour Tkinter and hex colour codes

Not sure exactly what you're looking for, but will this work?

import Tkintermycolor = '#%02x%02x%02x' % (64, 204, 208)  # set your favourite rgb colormycolor2 = '#40E0D0'  # or use hex if you prefer root = Tkinter.Tk()root.configure(bg=mycolor)Tkinter.Button(root, text="Press me!", bg=mycolor, fg='black',               activebackground='black', activeforeground=mycolor2).pack()root.mainloop()

If you just want to find the current value of the window, and set widgets to use it, cget might be what you want:

import Tkinterroot = Tkinter.Tk()defaultbg = root.cget('bg')Tkinter.Button(root,text="Press me!", bg=defaultbg).pack()root.mainloop()

If you want to set the default background color for new widgets, you can use the tk_setPalette(self, *args, **kw) method:

root.tk_setPalette(background='#40E0D0', foreground='black',               activeBackground='black', activeForeground=mycolor2)Tkinter.Button(root, text="Press me!").pack()

Then your widgets would have this background color by default, without having to set it in the widget parameters. There's a lot of useful information provided with the inline help functions import Tkinter; help(Tkinter.Tk)

The default color for Tkinter window I found was #F0F0F0

rudivonstaden's answer led me to a solution to the problem, although for some reason root.cget("bg") fails because "bg" is an unknown color name.

However, knowing that a widget has a dictionary containing its properties means that root["bg"] returns the background color of the widget.

So if you create a window named myWindow without overriding your system's default background color, then myWindow["bg"] is the default background color for a window, which can be used when creating frameless text fields within that window.
