According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text. It's advisable to test the color combination using accessibility tools to ensure compliance.

For backgrounds, use a lighter shade in combination with the #1B3BBB color to create a more accessible experience.
