The hex color #103A8B, also known as Congress Blue, presents some accessibility challenges due to its relatively low luminance. When used as a foreground color, it's crucial to ensure sufficient contrast against the background 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 and graphical elements. Using online contrast checkers can help determine if the color combination passes accessibility requirements. If the color is used in website designs, designers should pair it with lighter background colors such as whites (#FFFFFF), light grays (#D3D3D3) or lighter shades of blues or greens to make text readable for users with visual impairments. Also, avoid using this color for essential interactive elements without proper contrast because this will cause a negative impact on user experience. It is advisable to consider alternative, more accessible colors if contrast cannot be adequately improved.
