The color #284B9F, also known as Sapphire, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it is crucial to ensure that the foreground text or elements have sufficient contrast to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Lighter colors like whites (#FFFFFF) and very light yellows or greens may work well as foreground colors. Tools like WebAIM's Contrast Checker can assist in verifying contrast ratios. Additionally, providing alternative cues, such as icons or text descriptions, can benefit users with color vision deficiencies. Avoid using color as the sole means of conveying important information; supplement it with text or other visual indicators to ensure inclusivity. Careful consideration of font size and weight can also improve readability against this deep hue.
