In a post I wrote a while back about dark mode and variable fonts, Gerhard Großmann made this rather lovely comment:
In typography it’s well known that luminous letters on dark backgrounds tend to look bolder. Unfortunately I know the technical term only in German – „Überstrahlung“, which could be translated as blooming or flare. If somebody knows the English term, please comment! I found a good explanation of this effect in a German article about legibility on computer screens. My translation of the relevant part: “Bright areas outshine (flare/bloom into) darker ones, so that a bright background eats away dark letters from the outside and the font seems to be less bold – vice versa bright text seems to be bolder on dark backgrounds.” Besides on computer screens this effect occurs on luminous or reflective road signage, too [...]. It’s also helpful to slightly (!) letter-space white text on black backgrounds. As always in typography there’s more than one possibility to compensate the numerous subtle optical phenomenons.
Subtle. Optical. Phenomenons. Heck yes.Reply via email Random post
