The color #100DD9, a dark blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value means that text rendered in this color against a white or light background will have poor contrast, making it difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal-sized text and 3:1 for large text. This dark blue is unlikely to meet these ratios with lighter backgrounds, necessitating careful consideration of color pairings. Web developers should avoid using this color for primary text or essential interactive elements. If it is used, ensure that sufficient contrast is provided by using light-colored text on the dark blue background. Providing alternative high-contrast themes is a good practice to ensure accessibility for all users.
