Thank you for your consideration.
It’s a shame one cannot on-demand swap-in the black base for the two shared colors and forego the parallax visual effect entirely (like on the right-hand side of the screen).
Of the four screenshots you shared, Image 3 looks to provide the best contrast: the white ball (which is the most crucial game element that the player must visually lock-in on) shows up reasonably against the darkest grey and red.
