Change Ruler Color and Make Ruler "Hatch Marks" Larger

[BrandonBB]

How do I change the color of the ruler on my image as well as make the "hatch marks" larger in size? I can't see them that well with the current gray color.

You are using the light grey interface in Preferences, which does not have the best contrast

The lightest interface colour has more contrast, but is not the best for assessing your images because of how bright it is.  The markings are easier to see though.
