#150BA8

General Information about Ultramarine

The color #150BA8, known as Ultramarine, is a deep and intense shade of blue that sits between traditional blue and violet on the color spectrum. It derives its name from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally imported from regions beyond the sea. Historically, ultramarine was derived from the semi-precious stone lapis lazuli and was highly prized, often more valuable than gold. The synthetic production of ultramarine in the 19th century made it more accessible and affordable. Today, it is widely used in various applications, including art, design, and manufacturing, lending a sense of depth and sophistication to any project.

The hex color #150BA8, also known as Ultramarine, presents some accessibility challenges, particularly regarding contrast. When using this color for text or user interface elements, it's crucial to ensure sufficient contrast with the background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. Given its dark nature, Ultramarine necessitates a very light background color to meet these standards. Failure to do so can result in readability issues, especially for users with visual impairments. Tools like contrast checkers can help evaluate and adjust color combinations to comply with accessibility standards, promoting inclusivity and usability for all users.
