About Ultramarine

Ultramarine, represented by the hexadecimal color code #0D178E, is a deep, rich shade of blue. It belongs to the blue color family and is known for its intense and captivating appearance. Historically, Ultramarine was derived from the precious gemstone lapis lazuli, making it a highly valued pigment in art. Today, synthetic versions offer the same vibrant hue at a more accessible cost. In color psychology, Ultramarine is associated with depth, stability, and wisdom. It is often used to evoke feelings of trust and confidence, making it a popular choice for branding and design in various industries. Its high saturation and dark tone make it suitable for creating focal points and adding a touch of elegance.

The color #0D178E, also known as Ultramarine, presents significant accessibility challenges, especially when used as a background color for text. Its dark hue results in a low contrast ratio with lighter text colors like white or yellow, potentially making the content difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for readability. To improve accessibility, consider pairing #0D178E with a much lighter color to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. If using it for interactive elements like buttons, provide clear visual cues for focus states. Also, avoid using this color as the sole indicator of functionality, as colorblind users might miss the information.
