That is not the Command Bar, that is the Search Box text color  that you want to change. You have to change it in SkinStudio. Go to Theme part details, Command Bars, Search field background and select the Extra Settings tab, you can change the color there. 

Is that one of my skins, on Windows 10? If so let me know so I can fix it, thanks.

Are you using Windows 7, 8, or 10? If that is The Library, then who changed the Search Field image? That is not the image I put into the skin.

The only other thing you might try is changing the Button Text color in Change skin colours, then use the dropdown to select the Show me the skin defined system colours area. Change the Button Text color there.

Oh yeah, the toolbar buttons text colors, thanks Dave! Been a long day and I forgot about those.   

I am using Windows 10 with the latest updates and "Old New Explorer".  Figured out where it was..

Controls/Toolbars/Normal Toolbars/Button (6 state) [Text]tab.

Thanks DaveRI and LightStar for pointing me in the right areas    

Now using "The Library" (slightly modified by me for my daily use until LightStar releases the next skin)!
