General Information about Ultramarine (#0F1488)

The hexadecimal color code #0F1488 represents a dark shade of blue, often referred to as ultramarine. It is composed of 5.9% red, 7.8% green, and 53.3% blue. In the RGB color model, this translates to 15 red, 20 green, and 136 blue. This color falls into the blue-violet spectrum and is known for its depth and intensity. Ultramarine has historical significance, originally derived from the mineral lapis lazuli and highly valued as a pigment in Renaissance paintings. Today, synthetic ultramarine is widely available, offering the same rich color at a more accessible price. The color is often associated with royalty, intellect, and the ocean. Its evocative nature makes it a popular choice in various creative fields, from graphic design to fashion.

The color #0F1488, a deep ultramarine, presents significant accessibility challenges, especially for users with visual impairments. Its low luminance value of 3 means it provides insufficient contrast against light backgrounds, making text or interactive elements difficult to discern. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to ensure readability. This color likely fails to meet these standards when paired with common background colors like white or light gray. Therefore, it's crucial to use this color sparingly for text or interactive elements. When it is used, pair it with a very light color (e.g., #FFFFFF) to improve the contrast ratio and ensure that users can perceive the content effectively. Provide alternative styling options that allow users to customize the color scheme to their preferences.
