The hex color #304DB6, also known as Cerulean Blue, offers moderate accessibility. Its contrast ratio against pure white (#FFFFFF) is approximately 3.4:1, which doesn't meet the WCAG AA standards for normal text (4.5:1) but is close. For larger text sizes (14pt bold or 18pt regular), it nearly satisfies the 3:1 ratio. When used as a background, it's best paired with lighter text colors like white or very light grays to ensure readability. Darker text on a Cerulean Blue background may be challenging for users with visual impairments. To improve accessibility, consider using a lighter shade of blue or a darker text color to increase contrast. Testing with accessibility tools is recommended to validate the color combination's suitability for a wide range of users.
