In color theory, this color evokes feelings of trust, stability, and depth, which are often associated with the color blue.

The hex color #0310E3, a deep dark blue, presents significant accessibility challenges, especially in web design. Its low luminance value means it offers very little contrast against light backgrounds, making text and interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for readability. For normal text (size 14 points or 18 pixels and above) the contrast ratio should be at least 4.5:1, while for large text (size 18 points or 24 pixels and above) it should be at least 3:1. To ensure accessibility when using #0310E3, it is imperative to pair it with a very light color such as white or a very pale yellow to achieve an acceptable contrast ratio. Designers should use contrast checking tools to verify compliance with accessibility standards and consider the needs of all users, including those with low vision or color blindness. Avoiding its use for critical UI elements is also a wise choice.
