Coral Pixels is pretty nice with a lighter background, but unreadable with a dark one.

Have you tried a darker background but with an inverted color filter on the text? (I'd try it myself but I'm not at my computer for this post)

No, I was just checking it out on Google Fonts and I could not see a way to change the colours of the sub-pixels which is affecting the readability.
