Because of this, it makes sense why the button with white text is easier to read ( source). White is pure luminance with no hue or saturation, which is the strongest form for contrast. The WCAG contrast ratios donвЂ™t always account for the high luminance contrast of white text. This contrast inaccuracy seems to occur with white text on blue and orange backgrounds. Not only did normal-visioned users find the white text easier to read, but color-blind users did as well ( source). According to the contrast requirements, the button with white text should be less readable, but itвЂ™s actually more readable.ДЄ similar study comparing white and black button text confirms this finding. However, the contrast ratio for the white text is 2.94, which fails it. The contrast ratio for the black text is 5.41, which passes the requirement.

But the accessibility color contrast ratios tell a different story. When you survey users on which button is easier to read, the majority will tell you the button with the white text is more readable ( source). Both buttons below have a blue background, but one has white text, and the other has black. One case where the WCAG standards arenвЂ™t applicable is with the brightness contrast of white text. Instead of following them dogmatically, you should use them to guide your design decisions, not dictate them. However, these guidelines do not always measure up in practical application. The Web Content Accessibility Guidelines ( WCAG) is a set of principles used as the standard for determining accessible color contrast. Myth 1: The WCAG requirements are always optimal This article debunks common color contrast accessibility myths and sets the record straight. Not only that, but they assume an interface is inaccessible whenever color contrast is used to convey information.Д«ecause of this, designers often feel the need to obsess over accessibility, and are misled into believing their interface isnвЂ™t accessible when it actually is. They often parrot these myths to discredit a design, without understanding in which situations a color contrast standard applies. ItвЂ™s important to accommodate users with disabilities, but there are many myths to color contrast accessibility being perpetuated by misinformed people. ThereвЂ™s a growing demand for designers to make their interfaces accessible to all users.
