#020B91

General Information about Ultramarine

The color #020B91, commonly known as Ultramarine, is a deep and intense shade of blue. It sits within the blue color family, possessing a rich and vibrant quality. Historically, ultramarine pigment was derived from the semi-precious stone lapis lazuli, making it a highly valued and expensive pigment, especially during the Middle Ages and Renaissance. Its name originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was imported to Europe from Asia. Today, ultramarine is synthetically produced, making it more accessible and affordable. This color is often associated with royalty, trust, and wisdom, evoking a sense of depth and sophistication.

The hex color #020B91, also known as Ultramarine, presents significant accessibility challenges, especially when used as a background color for text. Its extremely low luminance makes it difficult for individuals with visual impairments to perceive text clearly. According to WCAG guidelines, sufficient contrast between text and background is crucial. For small text (less than 18pt), a contrast ratio of at least 4.5:1 is recommended, while for large text (18pt or larger), a ratio of 3:1 is required. Ultramarine falls far short of these recommendations when paired with standard light-colored text like white. To improve accessibility, consider using a lighter shade of blue or pairing it with a very light or bright contrasting color for text. Avoid using it as a primary background color for large blocks of text. Tools like contrast checkers can help determine if the color combination meets accessibility standards.
