Hey, would adjusting active title bar properties help?
On desktop empty area->right click->personalize->window color->advanced appearance settings->click where it say "Active Window" and adjust the properties
Or perhaps you would like to check out a high contrast theme? Open personalize as above, scroll down on the right, select one of the themes.
I guess there are customization tools as well that you can use to change the appearance further but I have no experience with them. Hopefully someone else will comment if these won't help you.
