html background set to match dialog background?

Hi I want my html background to blend in with my dialog. On windows, I'm using

  dlg_background = wx.SystemSettings.GetColour(wx.SYS_COLOUR_3DFACE)
  html.SetBackgroundColour(dlg_background)

Which seems to work just fine.

On the mac, this shade of gray is just a bit too dark.

How do I find the equivalent on the Mac?

Robin! So sorry to hear about OSAF not supporting you as much as before! I
wish you all the best.

Thanks,
