When used as a background color, it's crucial to ensure that the foreground text provides sufficient contrast to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using a very light color like white or a pale yellow as the text color on a #1A3759 background would improve readability. For users with visual impairments, including those with low vision or color blindness, adequate contrast is essential. Avoid pairing #1A3759 with other dark colors, as this could make content difficult to perceive. Consider using accessibility checkers to verify contrast ratios and ensure your design is inclusive.
