About Ultramarine

The hex color #1C0398, commonly known as Ultramarine, is a deep and vibrant shade of blue that falls within the blue-violet spectrum. It derives its name from the pigment originally made from ground lapis lazuli stone, a precious and expensive material. This color is associated with qualities such as royalty, wisdom, and spirituality. In the RGB color model, #1C0398 is composed of 11% red, 1% green, and 60% blue. Its corresponding values in the CMYK color model are 73% cyan, 99% magenta, 0% yellow, and 40% black. This makes it a highly saturated and intense color. Ultramarine is often used to evoke feelings of trust, stability, and depth, making it popular in branding and design.

The hex color #1C0398, also known as Ultramarine, presents some accessibility challenges, especially in web design. Due to its deep, saturated nature, it offers low contrast when paired with lighter text colors like white or yellow. This can make it difficult for users with visual impairments to read the content. According to WCAG guidelines, sufficient contrast is crucial for readability. To improve accessibility, consider using lighter shades of Ultramarine for backgrounds and pairing it with high-contrast text colors such as white or very light grays. Additionally, avoid using this color for critical interactive elements without clear visual cues and textual labels to ensure usability for all users, including those with cognitive disabilities.
