Ultramarine

#130B8D

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #130B8D, is a deep, vivid blue pigment that has been prized since antiquity. Derived originally from the semi-precious stone lapis lazuli, it was highly valued for its intense color and durability, often reserved for use in religious paintings and other works of high importance. The name 'ultramarine' literally means 'beyond the sea,' referring to the fact that the pigment had to be imported to Europe from mines in Afghanistan. Today, synthetic ultramarine is widely available, making it more accessible for various applications, while retaining its characteristic depth and richness. Its unique spectral properties cause it to appear particularly vibrant under certain lighting conditions, contributing to its enduring popularity in art, design, and other creative fields.

The color #130B8D, a deep Ultramarine, presents significant accessibility challenges, especially for users with visual impairments. Its low luminance value (approximately 3) means that text rendered in this color requires a very light background to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #130B8D, careful consideration must be given to the background color and text size to meet these standards. Tools like contrast checkers can be invaluable in determining appropriate color pairings. Furthermore, avoid using this color for critical interactive elements like buttons or links without clear visual cues beyond color alone, as color blindness affects a significant portion of the population.
