#040296

General Information about #040296

The hexadecimal color #040296, also known as Ultramarine, is a very dark shade of blue. It resides in the blue color space, characterized by a strong presence of blue pigment and minimal red or green. This color is often associated with depth, sophistication, and stability. Ultramarine has historical significance, originally derived from the precious mineral lapis lazuli. Due to its rarity and expense, it was highly valued by artists and used in important works of art. Today, synthetic ultramarine pigments are readily available, making the color more accessible. In color theory, #040296 is considered a cool color, often evoking feelings of calmness and serenity. It can be used to create a sense of formality or importance.

The color #040296, a deep ultramarine, presents significant accessibility challenges. Its extremely low luminance (very dark) results in poor contrast against lighter backgrounds, making it difficult for users with visual impairments to read text or discern important UI elements. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. A large text requires a contrast ratio of at least 3:1, while normal text requires at least 4.5:1. This color is unlikely to meet these standards against common background colors like white or light gray. Web developers should avoid using #040296 for text or interactive elements unless paired with a very light color that provides adequate contrast. Consider using a color contrast checker to ensure compliance with accessibility standards. Also, provide alternative styling options to ensure users can override the default color scheme to meet their needs. Proper use of ARIA attributes can further enhance accessibility when dealing with complex interfaces.
