set_bg_color followed by set_fg_color problem

[davidw]

When I do this, it causes the bg color to not get set.

    header_format.set_bg_color(0x98AAEE)
    header_format.set_fg_color(0x000000)

@davidw did you try setting font color instead?

header_format.set_font_color('000000')

[davidw]

I don't recall, at this point.
