Ultramarine
General Information About Ultramarine
Ultramarine, represented by the hexadecimal color code #1B0FA4, is a deep, vivid shade of blue. It derives its name from the pigment originally made from ground lapis lazuli stone, a semi-precious stone mined primarily in Afghanistan. Historically, ultramarine pigment was highly prized and expensive, often reserved for the most important figures and elements in paintings. In the RGB color model, #1B0FA4 is composed of 10.6% red, 5.9% green, and 64.3% blue. In the CMYK color model, it is composed of 83% cyan, 91% magenta, 0% yellow, and 36% black. This color evokes feelings of depth, stability, and sophistication. It is often associated with trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven.
The color #1B0FA4, also known as Ultramarine, presents several accessibility considerations for web developers. Due to its deep, saturated hue, it is crucial to ensure sufficient contrast when used as a background or text color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to ensure readability for users with visual impairments. When using Ultramarine as a background, pairing it with light colors like white, light yellow, or very pale blues can help achieve the necessary contrast. Conversely, using it for text requires a very light background color to maintain readability. Avoid using it for small text or important interactive elements if sufficient contrast cannot be achieved. Color blindness simulators can be useful tools to test how this color is perceived by individuals with different types of color vision deficiency. Proper use of ARIA labels and alternative text descriptions for images is also important to ensure usability for screen reader users.
