Question about wx BoxSizer background

[Gandalf]

I'm creating a table with gridSizer,  and I'm trying to set cell
background like I use to do with HTML

so I tried this:
BoxName =wx.BoxSizer(wx.HORIZONTAL)
BoxName.SetBackgroundColour('#cce8fa')

and it told me their is no sauce function

so what is the right way to do it?


thanks!
