General Information about Ultramarine

#1D0BA8, also known as Ultramarine, is a deep and rich blue color that evokes feelings of sophistication, mystery, and tranquility. It belongs to the blue color family and has a relatively low lightness value, making it appear quite dark. In the RGB color model, it is composed of 11.4% red, 4.3% green, and 65.9% blue. In the CMYK color model, it consists of 83% cyan, 93% magenta, 0% yellow, and 34% black. Ultramarine has a long history of being used in art, particularly in paints and pigments. Historically, it was derived from the precious stone lapis lazuli, making it highly valued. Today, it is synthetically produced, allowing for broader applications in various industries. It is used in web design, graphic design, fashion, and interior design to create sophisticated and eye-catching visuals.

The color #1D0BA8, a deep ultramarine, presents several accessibility considerations for web design. Its low lightness value means that it requires careful attention to contrast ratios when used for text or interactive elements. According to WCAG guidelines, sufficient contrast is essential for users with visual impairments. When using #1D0BA8 as a background, ensure that any foreground text has a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Lighter shades of yellow, white, or gray work well as foreground text colors. Avoid using it with darker colors, as the contrast will likely be insufficient. Also, consider providing alternative visual cues besides color to convey meaning, as color blindness affects a significant portion of the population. For example, use icons or text labels in addition to color to differentiate between elements.
