I just use panels for this sort of thing. You can set the color of the panel several different ways: you can use a named color, a wx.Color object, a predefined wx.Color object like wx.RED or a tuple of 3 integers.

Here's a simple example:

import wx

class MyPanel(wx.Panel):

    def __init__(self, parent):
        wx.Panel.__init__(self, parent)

        self.SetBackgroundColour('white')

        main_sizer = wx.BoxSizer(wx.VERTICAL)
        for number in range(5):
            btn = wx.Button(self, label='Button {}'.format(number))
            main_sizer.Add(btn, 0, wx.ALL, 5)

        self.SetSizer(main_sizer)


class MyFrame(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, title='Background colors')
        panel = MyPanel(self)
        self.Show()

if __name__ == '__main__':
    app = wx.App(False)
    frame = MyFrame()
    app.MainLoop()
