#030718

General Information about #030718

The hex color #030718, also known as Blue Charcoal, is a very dark shade that lies within the blue color family, though its darkness mutes the blue substantially. It is composed of 1.18% red, 2.75% green, and 9.41% blue. In the RGB color space, this translates to values of R:3, G:7, and B:24. Because of its extremely low values, the color appears almost black to the naked eye. Its primary characteristic is its depth and subtlety, making it suitable for applications where a hint of color is needed without being overtly bright or attention-grabbing. The color is often perceived as sophisticated and understated, lending itself well to designs that aim for a modern and minimalist aesthetic. In the context of web design, this color requires careful consideration of contrast ratios to ensure accessibility for all users.

The hex color #030718, also known as Blue Charcoal, presents significant accessibility challenges, especially in text-based applications. Due to its very low luminance, achieving sufficient contrast with foreground elements is difficult. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability for users with visual impairments. This color necessitates extremely light foreground colors (e.g., almost pure white) to meet these contrast standards. Therefore, when using #030718 as a background, careful consideration must be given to the choice of text color and font size. For interactive elements like buttons or links, the color contrast becomes even more crucial to ensure that users can easily identify and interact with them. Providing alternative high-contrast themes or allowing users to customize the color scheme are effective strategies to mitigate accessibility issues associated with this dark color.
