đ Never Use White Text on a Black Background
Jessica Otis @ jessicaotis.com: âEvery conference I go to, there will be at least one (and more often ten or twenty) presentations that use white text on a black background. These slides range from hard-to-read to outright illegible and in particularly bad set-ups are so visually painful that I have to close my eyes or turn away from the projection screen. [âŠ]
So please, everyone, strike white text with black backgrounds from your color repetoire, the same way youâve removed color combinations that are illegible to color-blind people. Itâs not a question of preferences, itâs an accessibility issue.â
astigmatism or halation effect with many lines of white text on a black background:
a few years ago i stumbled upon this nice little article explaining why the author canât read white text on a black background.
the same is happening to me when iâm using the dark mode on a few websites1 or apps.
most of them arenât pure white text on pure black background anymore and in some apps both the light and dark themes are customisable, but when i use apps like chatgpt or threads, or try to follow a fast moving twitch chat, i immediately have to enable the light mode or else my eyes will hurt and iâll suddenly get this astigmatism/halation effect on the white text as pictured above.
i really like louie mantiaâs blog, but reading it hurts my eyes↩
