When working with this color, it's important to consider its low luminance value, which impacts its accessibility against different background colors.

The hex color #1A345A, also known as Cello, presents some accessibility challenges, especially when used for text or interactive elements. Its relatively low luminance value of 0.027 means it offers poor contrast against a standard white background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability for users with moderate visual impairments. This color falls short of these recommendations when paired with white. To improve accessibility, consider using #1A345A with lighter colors such as light greys, yellows, or pastel shades to ensure sufficient contrast. Additionally, avoid using it for crucial information or interactive elements without proper contrast adjustments. Providing alternative color schemes or user-adjustable contrast settings can further enhance the user experience for individuals with diverse visual needs. When using this color for decorative purposes, consider its impact on users with color deficiencies and provide alternative visual cues where necessary.
