Some type designers are cleverly making use of the rise in popularity of dark mode interfaces. They're arguing that type looks different white on black (as usually in dark mode) compared to black on white, and are offering solutions to counter this.https://www.daltonmaag.com/library/darkmode
Personally, I think dark mode interfaces are a little overrated to begin with. Setting that aside, I'm wondering whether it makes much sense to design special typefaces for it. Is the white on black thing really an optical illusion, or is it about how displays rasterize white vs black pixels? Does it make sense to adjust anything other than weight? How about ink traps?
Just some thoughts, curious to hear your opinions.
