General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1D10A4, is a deep and vivid shade of blue. Historically, the pigment Ultramarine was derived from the mineral lapis lazuli, making it a highly prized and expensive color used predominantly in art and decoration. In modern color theory, Ultramarine is positioned as a primary color in the subtractive color model (CMYK), often used in printing. In the RGB (red, green, blue) color model, used for digital displays, Ultramarine is composed of relatively low red and green values, with a high blue value, contributing to its characteristic hue. This hex color is often associated with royalty, depth, and stability, and is used to evoke feelings of trust and sophistication in design and branding. Its rich tone makes it a popular choice for creating visually striking and memorable compositions.

The color #1D10A4, also known as Ultramarine, presents some accessibility challenges, particularly when used as a foreground color against a white or light-colored background. Its relatively low luminance (brightness) can result in insufficient contrast, making it difficult for users with visual impairments to read text or discern important interface elements. According to WCAG (Web Content Accessibility Guidelines), the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Ultramarine often falls short of these requirements when paired with lighter backgrounds. To improve accessibility, consider using Ultramarine sparingly for purely decorative purposes or pairing it with a much lighter color, such as a bright yellow or pale cyan, to guarantee enough contrast. Tools for calculating contrast ratios can accurately determine whether a color combination meets accessibility standards. Also consider using the color for larger elements such as titles or graphics.
