A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Using online contrast checkers can help verify compliance. Lighter colors like whites, yellows, or light greens generally work best as foreground colors against #1F3349. Avoid using similar dark shades as text, as this reduces readability. In cases where sufficient contrast cannot be achieved, consider using a different color palette or adding visual cues such as borders or icons to improve usability for users with visual impairments. Careful consideration of color combinations is essential for creating an inclusive and accessible design.
