Its prominence in art and design stems from its rich, saturated hue, making it a popular choice for creating visually striking effects.

The color #120F8B, a deep shade of blue often called Ultramarine, presents several accessibility challenges, particularly in web design. Its low luminance value of approximately 3% means that it offers very little contrast against standard white backgrounds. According to WCAG guidelines, sufficient contrast is crucial for readability, especially for users with visual impairments. Text or interactive elements using #120F8B on a white background would likely fail accessibility standards, making it difficult for many users to perceive the content. To improve accessibility, consider pairing #120F8B with very light colors like white or using a much lighter shade of blue or other complementary color as the background. Alternatively, increasing the font size and weight can somewhat improve readability, but it's not a guaranteed solution. Proper color contrast is not just about aesthetics; it's about ensuring inclusivity and usability for all users, including those with low vision or color blindness.
