This color is created by mixing a moderate amount of red and green with a significantly higher proportion of blue, resulting in its characteristic deep blue hue.

The hex color #1A3DBC, also known as Persian Blue, presents certain accessibility challenges, especially when used as a foreground color against a white or light-colored background. Its relatively low luminance value requires careful consideration to ensure sufficient contrast for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #1A3DBC for text or interactive elements, it's crucial to verify that the contrast ratio meets these standards. A lighter shade of yellow or orange would provide a better contrast and thus increase readability. Tools like contrast checkers can help evaluate the compliance of color combinations. Pairing #1A3DBC with very light colors or using it for purely decorative purposes can mitigate these issues. Furthermore, providing alternative cues like underlines or icons can enhance accessibility for users who may struggle with color perception.
