General Information about #01405D

The hexadecimal color code #01405D represents a dark shade of cyan-blue. It is composed of 0.39% red, 25.1% green, and 36.47% blue. In the RGB color model, #01405D is described as (1, 64, 93). This color is generally associated with feelings of tranquility, depth, and stability. It is often found in corporate branding and design where reliability and professionalism are desired. In terms of light and darkness, it is a relatively dark color, implying that it absorbs more light than it reflects. Due to its dark nature, it is important to consider contrast ratios when using it for text or other elements to ensure readability.

The color #01405D, also known as Astronaut Blue, presents significant accessibility challenges, especially when used as text on a white background. Its low luminance (relative brightness) results in very poor contrast, falling far below the WCAG (Web Content Accessibility Guidelines) recommended contrast ratios for both normal and large text. This means users with visual impairments, including those with low vision or color blindness, will likely struggle to read text in this color. To ensure accessibility, it's crucial to pair this color with a very light color, ideally white (#FFFFFF) or a very light grey, and even then, the text size might need to be increased. Alternatively, consider using #01405D sparingly for decorative elements where readability is not critical. When using it for interactive elements like buttons, sufficient contrast must be guaranteed for hover, focus, and active states.
