> As it is often said in various designer forums, please avoid pure white (#FFFFFF) on black (here #111111), as it makes the text glow for the human eyes (therefore making it unreadable for long text). Instead, try to lower a bit the contrast on the text color.

If you want an objective measure for this, see APCA: https://www.myndex.com/APCA/?BG=000000&TXT=ffffff&DEV=G4g&BU...

From https://git.apcacontrast.com/documentation/APCA_in_a_Nutshel...: "Lc 90 is a suggested maximum for very large and bold fonts (greater than 36px bold), and large areas of color". White on black scores Lc 108.

It's the likely future replacement for the standard WCAG2 contrast checker (which becomes really inaccurate for dark mode and I don't think makes any suggestion about maximum contrast).
