General Information about #030815

The hex color #030815, also known as Blue Charcoal, is a very dark shade of blue, almost appearing black to the naked eye. It resides in the lower range of the color spectrum, possessing minimal brightness and saturation. Its RGB values are R:3, G:8, B:21, indicating a slight dominance of blue over red and green. This color is often associated with sophistication, mystery, and a sense of depth. In the realm of color psychology, very dark blues can evoke feelings of calmness and stability, but also sadness or solemnity if used excessively. Due to its low luminance, it's primarily used as a background color or in situations where a subtle, unobtrusive color is desired. It's rarely used as a primary color in designs due to its tendency to blend into the background.

The hex color #030815, also known as Blue Charcoal, presents significant accessibility challenges. Its extremely low luminance value makes it unsuitable for text or interactive elements without careful consideration of contrast. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, especially for users with visual impairments. Using #030815 as a background color necessitates very light text (e.g., white or near-white) to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. It's advisable to use contrast checking tools to ensure compliance. Furthermore, avoid using this color to convey important information through color alone, as it will be inaccessible to colorblind users. Consider providing alternative visual cues, such as icons or text labels, to ensure that the content is understandable to everyone. Proper semantic HTML can further enhance accessibility when using this color.
