General Information about Ultramarine

The color #1D04A6, commonly known as Ultramarine, is a deep, rich shade of blue that evokes feelings of depth, sophistication, and tranquility. In the RGB color model, it consists of 11.4% red, 1.6% green, and 65.1% blue. It falls under the blue color family, leaning towards the darker end of the spectrum. Ultramarine has a long history, originally derived from the precious gemstone lapis lazuli. This association gives it a sense of luxury and rarity. Its hexadecimal representation makes it easily identifiable and usable in digital design and web development. The color is widely used in art, design, and various other fields to convey a sense of stability, trust, and sophistication.

The color #1D04A6, also known as Ultramarine, presents some accessibility challenges, particularly when used for text or interactive elements. Its low lightness value (approximately 8%) means that it requires very light text (white or near-white) to achieve sufficient contrast for readability, according to WCAG standards. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using this color for backgrounds behind lighter elements can work, but careful consideration must be given to the foreground elements to ensure they meet these contrast requirements. When designing, tools such as contrast checkers can assist in verifying compliance. For users with low vision or color blindness, ensuring sufficient contrast is crucial for a positive user experience. Additionally, avoid using #1D04A6 as the sole means to convey important information, as some users may not be able to distinguish it effectively.
