General Information about #002843

The hex color #002843, often referred to as "Blue Whale," is a deep, dark shade of blue. In the RGB color model, it is composed of 0% red, 15.7% green, and 26.3% blue. It falls within the cool color spectrum and evokes feelings of calmness, stability, and sophistication. This color is often associated with corporate environments, technology, and trust. In terms of color theory, #002843 can be used to create both monochromatic and complementary color schemes. Its darkness lends itself well to providing contrast when paired with lighter colors. It is important to note that due to its low luminance, careful consideration should be given to accessibility when using it in designs, particularly regarding contrast ratios for text and interactive elements.

The hex color #002843, a deep, muted blue, presents several accessibility considerations for web development. Its low luminance value means it requires careful attention to contrast ratios, especially when used as a background or for text. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. For AAA compliance, these ratios increase to 7:1 and 4.5:1, respectively. Using #002843 for text on a white background will likely fail these contrast tests, necessitating either a lighter text color (e.g., white or light gray) or a lighter background color. Tools like contrast checkers can help ensure compliance. When using this color for interactive elements like buttons or links, consider adding visual cues beyond color alone, such as underlines, borders, or icons, to aid users with color vision deficiencies. Also, avoid using it as the sole indicator of focus state.
