About Ultramarine

The color #2208AC, commonly known as Ultramarine, is a deep, vibrant shade of blue with a slight hint of violet. It belongs to the blue color family and is characterized by its rich, intense pigment. In the RGB color model, Ultramarine is composed of 13.33% red, 3.14% green, and 67.45% blue. This color is often associated with feelings of calmness, stability, and wisdom, making it a popular choice for branding and design purposes. Ultramarine's historical significance dates back centuries, as it was originally derived from the semi-precious stone lapis lazuli. Due to its rarity and high cost, it was highly valued and often reserved for use in religious art and royal commissions. Today, synthetic pigments have made Ultramarine more accessible and widely used in various applications.

The color #2208AC, also known as Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When using Ultramarine as a background color, it's crucial to pair it with a light text color, such as white or a very light shade of yellow or gray, to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text, as specified by WCAG guidelines. For larger text (14pt bold or 18pt regular), a contrast ratio of 3:1 is acceptable. Avoid using Ultramarine with dark text colors, as this can make the text difficult or impossible to read for users with visual impairments. Additionally, consider providing alternative ways to convey information beyond color alone, such as using icons or text labels, to accommodate users who are colorblind. Proper color contrast testing tools can help verify compliance with accessibility standards.
