General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #010597, is a deep, saturated blue with a strong presence. It derives its name from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally imported from regions beyond the sea, notably Afghanistan where lapis lazuli, the source of the pigment, was found. The color is associated with royalty, wisdom, and spirituality. In art history, ultramarine was highly prized and costly, reserved for important figures and religious iconography, especially in depictions of the Virgin Mary. Today, synthetic ultramarine provides a more accessible alternative. The color has a RGB value of R:1, G:5, B:151 and a CMYK value of C:99, M:97, Y:0, K:41. It is mostly used as background color for websites or applications.

The color #010597, a deep ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 1.05 makes it difficult to achieve sufficient contrast against lighter backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This dark shade will likely require very light text colors (e.g., white or very pale yellow) to meet these contrast requirements. Careful consideration is needed to ensure that text and interactive elements are legible and easily discernible. Using online contrast checkers is essential to validate the chosen color combinations. Additionally, avoid using this color as the sole means of conveying information, as users with color blindness may not be able to distinguish it effectively. Providing redundant cues, such as text labels or icons, is crucial for ensuring inclusivity. Furthermore, consider the impact on users with low vision, who may benefit from increased text size and spacing to improve readability against this dark background.
