General Information About Ultramarine

The color #000C9B, also known as Ultramarine, is a deep shade of blue residing within the blue color family. In the RGB color model, it is composed of 0% red, 4.7% green, and 60.8% blue. The name 'Ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally imported from mines in Afghanistan by sea. Historically, ultramarine was a highly prized pigment, often more expensive than gold, and was reserved for the most important artistic commissions. Its association with royalty and religious figures contributed to its esteemed status. Today, synthetic ultramarine is readily available, making it an accessible and versatile color for various applications, including art, design, and fashion.

The hex color #000c9b, a deep ultramarine, presents significant accessibility challenges, primarily due to its low luminance. When used as a background color, it necessitates very light text to ensure sufficient contrast for readability, ideally achieving a contrast ratio of at least 4.5:1 as recommended by WCAG guidelines. Conversely, as a text color, it requires a very light background. It's crucial to avoid pairing it with colors of similar darkness or hues, as this can result in visual impairment, particularly for individuals with low vision or color blindness. Careful consideration of color pairings and luminance contrast is essential to guarantee an accessible and user-friendly design. Tools such as color contrast checkers can assist in verifying compliance with accessibility standards and identifying suitable color combinations.
