There is no “Myths of Color Contrast Accessibility”

  • A UX Movement article (covered in November) argued that text/background color combinations that fail the WCAG AA contrast threshold can actually be easier to read than those that pass. Geoffrey Crofte has written a counter-article arguing that the methodology of the original article was flawed, proposing his own combo (via useful tool color.review) that is both AA-compliant and is easier to read than the original. It’s worth noting the new contrast rating (4.5) is still lower than the ‘hard to read, but compliant’ original (5.41), but Geoffrey puts this down to context: a black background reverses the perception biases of the original article. Finally, Geoffrey disagrees that color alone can be used to denote state (see myth 6 in the original article), arguing that the toggle token example is difficult to read if no tokens are toggled by default.
New button has slightly darker blue and works better on both white and black backgrounds, compared to the original two buttons.
Geoffrey’s proposed color contrast scored highly with users and has a AA rating for contrast
