The hex color #2a09dd, a dark blue, presents some accessibility challenges, especially concerning color contrast. When used as a background color, it requires light-colored text to ensure readability. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. With #2a09dd, standard black text would fail this requirement. White or very light shades of yellow or green would be more appropriate choices to ensure sufficient contrast.

Using this dark blue sparingly and strategically, with careful consideration for contrast, can help mitigate accessibility concerns. For interactive elements like buttons, ensure hover and focus states also maintain sufficient contrast. Consider providing alternative high-contrast themes for users who need them.
