#1A0DAB

General Information about Ultramarine (#1A0DAB)

The hex color #1A0DAB, also known as Ultramarine, is a deep shade of blue with a rich history. Ultramarine derives from the Latin 'ultramarinus', literally 'beyond the sea', as the pigment was originally imported from Asia. Historically, it was made from ground lapis lazuli, making it one of the most expensive pigments available. In modern times, synthetic ultramarine is readily available. This color is often associated with royalty, intelligence, and stability. In color psychology, blue is often linked to trust, peace, and order. In digital design, understanding a color's history and associations can aid in effective branding and visual communication, impacting user perception and emotional response.

The color #1A0DAB, a deep ultramarine, presents some accessibility challenges, especially when used as a foreground color against a white or light-colored background. Its low luminance value (relative to white) means that text rendered in this color may not provide sufficient contrast for users with visual impairments. According to WCAG guidelines, the contrast ratio between foreground and background colors should be at least 4.5:1 for normal text and 3:1 for large text to meet Level AA compliance. When using #1A0DAB, careful consideration should be given to pairing it with a lighter color that provides adequate contrast. Tools are available to check color contrast ratios, ensuring that web content is accessible to a wider audience, including those with low vision or color blindness. For buttons and interactive elements, ensure sufficient visual cues beyond color to indicate state and purpose.
