The color #220BA8, a deep ultramarine, presents some accessibility challenges due to its low luminance. When used as a background color, it requires a very light text color to ensure sufficient contrast for readability, meeting WCAG standards for text legibility. Ideally, a text color like #FFFFFF (white) or a very pale yellow would be suitable. Using darker text colors, such as grays or blacks, would make the text difficult, if not impossible, for many users to read comfortably, particularly those with visual impairments. In interface design, avoid using this color for crucial interactive elements unless accompanied by clear visual cues and sufficient contrast ratios. Consider providing alternative high-contrast themes or color customization options to accommodate users with different visual needs. Larger font sizes and bolder text weights can also slightly improve readability against this dark background, but contrast should remain the primary consideration.
