Mint-L-Dark themes have too low of contrast between text and background

[NintendoManiac64]

Yes, I know about that eye vision health thing where full white text on a full black background is too high contrast and results in eyestrain and therefore is no good—that's not the issue.

I'm finding that the Mint-L-Dark themes go too much the other way and has too little contrast between the text and the background, particularly in Nemo/Caja/Thunar, causing me to...whatever the opposite of squint is called with regards to opening my eyes wider and trying to focus more, once again resulting in eyestrain (honestly more-so than I ever got with full-white text on a full-back background due to LCD's inherent terrible black levels relative to CRTs and OLEDs causing that "full-black" to be a "dark grey" anyway).

As a sanity check, I even took a screenshot and viewed it on an OLED phone, but even on there the poor contrast is evident.

A really easy reference is to just look here at github's own "dark mode" which definitely has better contrast and yet still has somewhat reduced contrast relative to the undesirable "full-white text on full-black background". An alternative example is the Adwaita-dark theme that's also included in Mint which, despite having less contrast than Github's own dark theme, still has more contrast than the Mint-L dark themes.
