General Information about #2B0CDB
The hexadecimal color #2B0CDB, often referred to as a dark blue or indigo, is composed of 17.1% red, 4.7% green, and 85.9% blue. It is commonly used in digital design, branding, and user interfaces to convey feelings of trust, authority, and intelligence. Darker shades of blue are often seen as professional and reliable, making them suitable for corporate logos and websites. In color theory, blue is associated with calmness and stability, but it can also evoke a sense of sadness when used excessively or inappropriately. Understanding the psychology behind color choices is important in both visual and physical design to affect a desired emotion or effect. This color in particular is very versatile in the way it can be used.
The color #2B0CDB, a dark blue, presents significant accessibility challenges. Its low luminance can make it difficult to read text rendered in this color against a white or light background. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This dark blue may not meet these requirements when paired with lighter colors. To improve accessibility, consider using a lighter tint of blue, pairing it with a very light or white text, or adding a dark overlay to lighter background images to increase the contrast. Additionally, avoid using this color as the sole indicator for interactive elements; provide alternative cues like underlines or icons to ensure that users can identify interactive elements, irrespective of their ability to perceive color differences.
