When used as a background color, sufficient contrast with foreground text is crucial. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using a light-colored text such as white or a very pale yellow can help achieve this contrast.

Tools like contrast checkers can accurately measure the contrast ratio between #2a45bc and text colors, ensuring compliance with accessibility standards. Employing ARIA attributes can further enhance accessibility by providing screen readers with additional contextual information.
