Its low luminance value of 2 means that text rendered in this color requires very light foreground colors to achieve sufficient contrast for readability. Following WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Given the darkness of #031298, it's crucial to pair it with colors like white or very light yellows to meet these standards. Failure to do so can exclude users with visual impairments, including those with low vision or color blindness. Careful consideration must be given to the size and weight of text when using this color to ensure it remains accessible to all users. Using accessibility analysis tools during the design phase is highly recommended to validate contrast ratios and identify potential issues before deployment.
