The hex color #0109B3, a dark blue, presents accessibility challenges, especially for users with visual impairments. Its low luminance contrast against lighter backgrounds can make text and interactive elements difficult to read. According to WCAG guidelines, sufficient contrast ratios are crucial for ensuring readability and usability. For normal text (14pt or 18px and larger bold text) a contrast ratio of at least 4.5:1 is needed. For large text (18pt or 24px) a contrast ratio of 3:1 is needed. To improve accessibility, consider pairing #0109B3 with much lighter colors like whites, creams, or light yellows to meet these contrast requirements. Alternatively, use this color for larger design elements where readability is less critical, or implement features like color customization to allow users to adjust the color scheme to their preferences. Adequate testing with accessibility tools is recommended to validate the contrast and ensure a more inclusive user experience.
