The hex color #284CAE, also known as Cerulean Blue, presents moderate accessibility challenges. Its luminance value necessitates careful consideration when choosing text and background color combinations. When used as a background color, white or very light shades of yellow or green are recommended for text to ensure sufficient contrast, typically aiming for a contrast ratio of at least 4.5:1 as defined by WCAG guidelines.

Adequate color contrast is vital for ensuring that content is accessible and perceivable to all users, including those with low vision or color blindness.
