The color #1611A3, a deep shade of ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance results in poor contrast against typical background colors like white, making text difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This color is unlikely to meet these requirements against light backgrounds. To enhance accessibility, consider using lighter text colors, such as white or yellow, against #1611A3, or pairing it with much lighter background colors. Tools like contrast checkers can help evaluate compliance with accessibility standards. Also, avoid using this color for essential visual cues without providing alternative indicators, like labels or icons.
