Its hexadecimal representation, #034DB0, is commonly used in web design and digital graphics. Cobalt blue has a long history, dating back to ancient civilizations where it was derived from cobalt oxide. Today, it is synthetically produced and widely used in various applications, from paints and dyes to plastics and ceramics. Its versatility and appealing aesthetic make it a popular choice in both artistic and industrial contexts.

The hex color #034DB0, also known as Cobalt, presents some accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 0.035 results in a poor contrast ratio against white backgrounds, making text and other elements difficult to read. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet WCAG AA standards. Therefore, using #034DB0 for text or essential UI elements against a white or light background is not advisable. To improve accessibility, consider using a lighter shade of blue or pairing it with a much darker background. Always test color combinations with accessibility tools to ensure sufficient contrast for all users.
