Proper contrast with lighter colors is essential for readability.

The color #010034, a very dark blue bordering on black, presents significant accessibility challenges, particularly in text-based applications. Due to its extremely low luminance, achieving sufficient contrast with lighter foreground colors is crucial for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This dark hue necessitates the use of very light colors like white or bright yellow to meet these standards. In situations where color conveys meaning, ensure that redundant cues (e.g., text labels, icons) are provided to assist users with visual impairments, including those with color blindness. It is essential to test the color combination with accessibility tools to confirm compliance with WCAG standards, ensuring that the content is perceivable and usable by a wide range of users.
