It is a primary color in the additive color model (RGB), meaning it is one of the three colors used to create all other colors on screens. In web development, #0000EF is often used to represent a pure, intense blue. Its hexadecimal representation indicates that there is no red (#00) or green (#00) component, with the maximum value assigned to the blue component (#EF).

Understanding its properties is crucial for effective use in both digital and traditional media.
The color #0000ef, a deep blue, presents specific accessibility challenges, primarily concerning color contrast. When used as text, it requires a light background to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This blue hue might not be suitable for users with visual impairments or color blindness if paired with dark or similar-toned colors. Ensuring sufficient contrast is crucial for conveying information effectively. Furthermore, avoid using this color as the sole indicator of interactive elements like links or buttons. Supplement it with text labels, icons, or underlines to make it accessible to all users. Consider using tools to evaluate color contrast ratios to guarantee compliance with accessibility guidelines.
