The color #0D168A, also known as Ultramarine, is a deep and saturated shade of blue in the blue-violet hue range. It is composed of relatively low red and green values and a very high blue value in the RGB color model.

Ultramarine traditionally refers to a pigment derived from the mineral lapis lazuli, renowned for its intense blue color. This color evokes feelings of depth, serenity, and sophistication. It's often associated with royalty, wisdom, and spirituality, making it a popular choice in various design applications where a sense of elegance and authority is desired.

The hex color #0D168A, a deep ultramarine, presents some accessibility challenges, especially when used for text. Its low luminance value (approximately 4) means it needs a very light background to provide sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using #0D168A on a white or slightly off-white background might not meet these standards, potentially causing visual strain for users, especially those with visual impairments. Therefore, when using #0D168A, it's crucial to pair it with a very light color to ensure optimal readability and accessibility. Testing the color combination with accessibility tools is highly recommended.
