General Information about Ultramarine

Ultramarine (#050D93) is a deep, vivid blue color that derives its name from the Latin "ultramarinus," meaning "beyond the sea," as it was originally imported from minerals found overseas. Historically, ultramarine was created by grinding lapis lazuli into a pigment, making it one of the most expensive and prized colors used by Renaissance artists. Today, synthetic versions of ultramarine are widely available, offering the same rich hue at a more accessible price. In color psychology, ultramarine is associated with depth, stability, trust, and intelligence. It evokes feelings of calmness and can promote a sense of security and confidence. Its hexadecimal triplet is 050D93, representing very low values of red and green and a high value of blue, reflecting its place in the blue color spectrum.

The color #050D93, also known as Ultramarine, presents considerable accessibility challenges due to its dark hue. When used as a background color, it requires very light text (white or near-white) to ensure 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 to meet AA standards. Ultramarine significantly fails to meet these standards with darker text colors. Therefore, to enhance accessibility, it's advisable to pair it with light color text, and conduct thorough testing with accessibility evaluation tools to confirm compliance. Also, avoid using it for interactive elements unless the visual cues are extremely clear and meet contrast requirements, especially for users with low vision or color blindness. Providing alternative styling options for users can further improve the experience.
