Change the colour of grey text back to black on website using poor contrast text
For a more future oriented version (as setting a font to black wont work with dark pages), check out the CSS Color Module Level 5 spec for color-contrast(), which will automatically choose a color that has a proper contrast ratio: https://www.w3.org/TR/css-color-5/#funcdef-color-contrast
One caveat is it's currently only supported in Safari technical preview.
Another thing worth mentioning is the relative brightness algo used in the repo for the linked plugin is using the WCAG 2 formula for relative luminance. This works pretty well in light mode for non-colored backgrounds, but doesn't incorporate perceived luminosity differences of different hues very well. A better algorithm to use here is the Advanced Perceptual Contrast Algorithm (APCA), which is the one used in the WCAG 3 working spec. It more accurately accounts for hue: https://github.com/Myndex/SAPC-APCA

Note the licensing note in the repository[1] of the APCA™ index the author’s company[2] promotes:

In this repositiory, all files present are under a time-barred beta license, and intended for use with web-based content only, and not for any other use without written permission.
The non-pre-release stuff[3] offered to W3C is better but still seems to be intended to end up non-FOSS:

(The question being, of course, how much of this is copyrightable at all.)

WCAG 3 and updated contrast checkers?
Second: There are a number of contrast checkers that use APCA technology. The canonical "official" one is https://www.myndex.com/APCA/ but I want to mention it is an open public beta, and is not backwards compatible with WCAG_2 (this is in part because WCAG_2 is not perceptually accurate and thus the areas where WCAG_2 incorrectly fails pairs that APCA will pass is at issue).
- WCAG 3 will use a new color contrast method called APCA
-
I made a tool to check the contrast between two colours using the new contrast algorithm being drafted for WCAG 3 — also includes fun rgb/hsl/lch sliders and buttons to adjust either colour to a desired contrast!

What color scheme do you use?
The only light themes I've been able to find with sufficient readability contrast (for me) that are more colorful than that are the light high-contrast version of github-nvim-theme, and Tempus Totus from tempus-themes. I'm sure there exist others, though.

zenbones or Tempus Totus

Light colorschemes with treesitter support
Protesilaos Stavrou's Tempus Themes are awesome. Super high contrast, great readability, very pragmatic. I'm partial to Tempus Totus and Tempus Past myself.

Dark Mattr - A new VS Code theme
Yeah, I feel like I'm taking crazy pills with all these zero contrast colorschemes popping up. Tempus Totus or GTFO!
