Difficult to see the Rulers bar

Hi All,

I just installed CorelDraw 2019 for MAC.  I'm having a lot of difficulty seeing the "Ruler" bar.

It's very gray and light in color. Is there any way I can make the numbers darker to see the

Rulers bar better.  Or maybe changing to a darker theme may help?  If so, how do I do that?

All help is appreciated.

Thanks
