The color #121489, a deep ultramarine, presents several accessibility considerations for web development. Its dark hue results in a low luminance value, which necessitates careful selection of foreground text colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Therefore, using white or very light shades of yellow or green would be advisable for text displayed against this background. The color should not be used as the sole indicator of important information, such as links or error messages; supplementary cues like underlines or icons should be added for users with color vision deficiencies. Thoughtful use of this color can make web content more inclusive and usable for individuals with varying visual abilities.
