White text on a black background provides higher visual contrast than black on white for specific visual conditions
the verdict
CONTESTED
the evidence cuts both ways
confidence 19/100
Evidence regarding whether white text on a black background provides superior visual contrast and performance is mixed, with some studies showing benefits for dark modes while others favor light modes or find highly individualized results.
