About Ultramarine (#1E05AE)

Ultramarine, represented by the hex code #1E05AE, is a deep blue color with a rich history. The name 'Ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally derived from lapis lazuli imported from Asia. This gemstone was ground into a powder to create the highly prized pigment, making it extremely expensive and reserved for important commissions, such as paintings of the Virgin Mary in the Middle Ages and Renaissance. Today, synthetic Ultramarine is widely available, offering the same vibrant hue at a fraction of the cost. It is valued for its non-toxic nature, lightfastness, and resistance to fading, making it a popular choice in various applications.

The hex color #1E05AE, also known as Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as a foreground color for text, it's crucial to ensure sufficient contrast against the background. A light background is generally recommended to meet WCAG (Web Content Accessibility Guidelines) standards for readability. Specifically, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Tools like contrast checkers can help verify compliance. Additionally, avoid relying solely on color to convey important information; provide alternative cues such as text labels or icons. When using #1E05AE for interactive elements like buttons or links, ensure that hover and focus states are clearly distinguishable to support users with visual impairments or those navigating with keyboards.
