About Ultramarine (#090C8F)

Ultramarine, represented by the hexadecimal color code #090C8F, is a deep, rich shade of blue. It is often associated with royalty, intelligence, and stability. In color theory, Ultramarine is considered a cool color, which can evoke feelings of calmness and serenity. The color's name originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally derived from the precious mineral lapis lazuli, imported from across the sea. This pigment was highly valued in Renaissance painting for its brilliance and depth of color. Today, synthetic ultramarine is widely available, making this beautiful hue more accessible for various applications. Its deep saturation and unique tone make it a favorite in design, art, and fashion.

The color #090C8F, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in low contrast against lighter backgrounds, making text and interface elements difficult to read. According to WCAG guidelines, sufficient contrast ratios are essential for ensuring content is perceivable. To improve accessibility, it is recommended to use this color with very light backgrounds, such as white or very pale yellows, to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, providing alternative text descriptions for images and using ARIA attributes can further enhance the user experience for individuals using assistive technologies. Avoid pairing this color with other dark shades or colors with similar luminance values, as this will exacerbate readability issues. Thoughtful color choices are crucial for creating inclusive and accessible web designs.
