The color #140F8B, a deep ultramarine, presents accessibility challenges due to its low luminance. When used as a background, sufficient contrast with text is crucial. A light text color, such as white or a pale yellow, is recommended to ensure readability. Tools like contrast checkers can verify compliance with WCAG guidelines, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, avoid relying solely on color to convey information; use supplementary cues like icons or text labels. Users with visual impairments or color blindness may struggle to distinguish this color from other dark shades, highlighting the importance of thoughtful design choices. Providing alternative color schemes or a high-contrast mode can further enhance accessibility for all users. Careful consideration of font size and weight also plays a significant role in improving readability against this dark background.
