How to make number row match the rest of the keyboard?

My phone theme has been black on black on black on black with a beautiful accent of color of more black since my very first smartphone. Why is there seemingly no control over the color of the number row on this otherwise amazing keyboard? I just upgraded my phone and am trying to go back to using SwiftKey after the last 18 months on my note 9 using gboard because their number row matches. SwiftKey is better there's no doubt about that but this dang gray bar in the middle of my screen makes it unbearable. So much customization except this one simple spot.
