# How to control style of GeoScaleBar?

I'm plotting the GeoScaleBar over satellite image and wish it to be white but cannot find an option which controls its styling:

GeoGraphics[{EdgeForm[Yellow], FaceForm[], Entity["Ocean", "BlackSea"]["Polygon"]},
GeoServer -> {StringTemplate[
"http://khms<*Mod[#2+#3,4]*>.googleapis.com/kh?x=2&y=3&z=1&v=196"],
"ZoomRange" -> {1, 21}},
GeoScaleBar -> Placed[Quantity[Range[0, 900, 100], "Kilometers"], Scaled[{.13, .25}]]]


(for future: in the above StringTemplate the version number of Google maps v=196 may require updating to the current version number).

How to control the styling of GeoScaleBar?

• It's very odd isn't it? You can say BaseStyle -> White and the line goes white and that's it. You can change the FontFamily, the FontSize, even the FontSlant, but FontColor has no effect. – Jason B. Feb 25 '16 at 14:22

Hmm, I can't find any way to give GeoScaleBar options, but all it does is produce some Line and Text graphics that we can alter after with some simple replacement rules:
    g = GeoGraphics[...];

You can see the structure of the graphic at g[[1,1]], towards the end are the Line and Text objects we're changing the formatting of.
