General Information About #0310E3
The hex color #0310E3, often referred to as a dark blue or deep indigo, is a color defined within the sRGB color space using a hexadecimal notation. It's composed of 1.2% red, 6.3% green, and 89% blue. This composition indicates a strong dominance of blue, hence its classification. In color theory, this color evokes feelings of trust, stability, and depth, which are often associated with the color blue. Due to its low lightness value (approximately 4.1%), this color appears quite dark. Colors with such characteristics are frequently used to create a sense of sophistication or mystery. When discussing color models, #0310E3 translates to RGB values of R:3, G:16, B:227, or expressed in percentages as R:1.2%, G:6.3%, B:89%.
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.
