General Information about #0015CA

The hex color #0015CA, often described as a dark blue, is a color defined within the sRGB color space. It is composed of 0% red, approximately 8.2% green, and nearly 80% blue. This high concentration of blue contributes to its deep and rich tone. Hex colors are commonly used in web design and digital graphics because they offer a standardized way to represent colors across different platforms and devices. Colors like #0015CA can evoke feelings of trust, loyalty, and sophistication, making them suitable for branding and design projects where these qualities are desired. Understanding the composition and properties of a hex color is essential for designers and developers seeking to create visually appealing and effective designs.

The hex color #0015ca, a deep shade of blue, presents some accessibility challenges, especially when used for text or interactive elements. Its low lightness value (around 4%) means that it requires very light text (ideally white or a very pale yellow) to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). When using #0015ca, careful consideration must be given to the foreground color to meet these standards. Tools like contrast checkers can be invaluable in assessing and verifying adequate contrast. Insufficient contrast can make content difficult or impossible to read for users with visual impairments, including those with low vision or color blindness. For purely decorative elements, contrast requirements are less strict, but providing alternatives for users who may struggle with the color is good practice.
