The hex color #284B54, also known as Blue Dianne, presents some accessibility considerations for web development. Its relatively dark hue means that careful attention must be paid to the contrast ratio when used with text or other foreground elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to ensure readability for users with visual impairments. Therefore, when using #284B54 as a background color, it's crucial to pair it with a light-colored text to meet these contrast requirements. Tools like contrast checkers can be used to verify compliance. If adequate contrast cannot be achieved, consider using a lighter shade of blue or a completely different color combination to ensure that the content remains accessible to all users, including those with low vision or color blindness.
