According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #0D4DDB for text on a white background may not meet these guidelines.

Always supplement color cues with text labels or icons to ensure usability for everyone. Proper use of ARIA attributes can also help convey meaning and improve accessibility for assistive technologies.
