The hex color #002799, also known as Smalt, presents significant accessibility challenges, particularly in text-based applications. Due to its very dark hue and low luminance value, it offers insufficient contrast against lighter backgrounds, such as white or pale yellow. This lack of contrast can make text illegible and cause visual strain for users, especially those with visual impairments or color vision deficiencies. To ensure accessibility, it is crucial to use #002799 sparingly and always pair it with high-contrast colors for text and interactive elements. A recommended approach involves using light text colors, such as white (#FFFFFF) or light gray (#D3D3D3), on a #002799 background. Tools like contrast checkers can help evaluate color combinations and ensure compliance with accessibility standards like WCAG, which provide specific contrast ratio requirements for different types of content. Avoid using this color for small text or critical interactive elements without thorough accessibility testing.
