General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #150c8c, is a deep, vivid blue hue often associated with royalty, sophistication, and the sea. Derived from the Latin 'ultramarinus,' meaning 'beyond the sea,' it historically referred to the pigment made from ground lapis lazuli, imported from far-off lands. In color theory, Ultramarine is considered a cool color, capable of evoking feelings of calmness, trust, and stability. Its rich and intense nature makes it a popular choice in various applications, including art, design, and fashion. The color's unique spectral properties contribute to its perceived depth and luminosity, making it visually striking and memorable. Due to its depth, care should be taken in ensuring sufficient contrast when used for text or interactive elements.

The hex color #150c8c, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in low contrast against light backgrounds, making text or interactive elements difficult to read. According to WCAG guidelines, sufficient contrast ratios are crucial for readability. To enhance accessibility, it is recommended to use #150c8c with very light backgrounds, ensuring a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Alternatively, consider using lighter shades of blue or pairing #150c8c with complementary colors that offer better contrast. Providing alternative text descriptions for images and ensuring that interactive elements have clear focus indicators are also essential accessibility practices when using this color.
