Improve design for accessibility/readability

Hey Wouter van Wijk and contributors, also Adam-Wilson and other maintainers of this beautiful project.

Old Design:

New Design:

Happy to alter a bit more for your preference.

This looks brilliant, it's much easier on the eyes and clearer. Thank you!
