General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #101A88, is a deep, rich shade of blue. Historically, ultramarine was derived from the precious stone lapis lazuli, making it one of the most expensive pigments. Today, synthetic versions provide a more accessible alternative, maintaining the color's vibrant and intense characteristics. In color psychology, ultramarine is often associated with trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven. It is known for its calming effects and is frequently used to evoke feelings of peace and tranquility. It belongs to the blue color family and sits between blue and violet on the color spectrum.

The hex color #101A88, also known as Ultramarine, presents several accessibility considerations for web developers. Its dark hue means it generally requires light-colored text for sufficient contrast. When using this color for backgrounds, ensure the foreground text meets WCAG (Web Content Accessibility Guidelines) AA or AAA standards for contrast ratios. Tools are available to check contrast ratios to ensure readability for users with visual impairments. Avoid using this color for elements that need to convey critical information alone, as colorblind users might not be able to distinguish it effectively. Consider providing alternative visual cues, such as icons or text labels, to support usability for all users. Proper use of ARIA attributes can also enhance accessibility for screen reader users.
