The color #0342B1, a deep cobalt blue, presents some accessibility challenges, particularly when used as text against a white background. Its low luminance contrast ratio may not meet WCAG standards for normal text, potentially causing readability issues for users with visual impairments. To enhance accessibility, consider using it for larger text elements or graphical accents where legibility is less critical. When using this color for text, pair it with a light color such as white or a light shade of yellow to ensure a sufficient contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Alternatively, combining this color with darker shades can create a harmonious palette while addressing accessibility needs. Proper testing with accessibility tools is essential to ensure compliance with accessibility guidelines and provide an inclusive user experience.
