General Information about #031017
The hexadecimal color code #031017 represents a very dark shade of blue-gray, often referred to as Blue Charcoal. It's composed of 1.18% red, 6.27% green, and 9.02% blue. In the RGB color space, it has values of R:3, G:16, and B:23. In the CMYK color space, its values are C:0.87, M:0.30, Y:0.00, and K:0.91. The color has a very low luminance, making it appear almost black. Its primary function is to provide a dark backdrop, lending a sense of depth and sophistication. Blue Charcoal is often used in designs where a subtle, understated tone is desired, steering clear of the starkness of pure black while still offering a strong, grounding presence.
The hex color #031017, also known as Blue Charcoal, presents significant accessibility challenges. Its extremely low luminance value (very dark) results in poor contrast against most background colors, especially white. According to WCAG guidelines, sufficient contrast is crucial for readability and usability, particularly for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #031017 for text on a white background, or even lighter shades, would fall far short of these recommendations, making it difficult for many users to perceive the content. Therefore, using #031017 as a primary text color should be avoided. If it's used as a background color, ensure that any text or interactive elements on top have sufficient contrast, potentially requiring very light or bright colors to meet accessibility standards. Tools like contrast checkers can help evaluate the contrast ratio and suggest alternative color combinations that are more accessible.

Applications
Web Development Background
In web development, #031017 can be employed as a background color for website sections or footers to create a dark and sophisticated aesthetic. Due to its low luminance, it is not suitable for text. It can be effectively combined with lighter accent colors, such as off-white or light grays, to maintain readability and visual appeal. Consider using it for decorative elements, such as borders or dividers, to add depth without compromising accessibility. In user interface (UI) design, it could be part of a dark theme, but careful attention must be paid to the contrast ratios of all elements placed on top of it. It's well-suited for websites that aim for a professional, modern, or even slightly mysterious feel.
Interior Design Accent
In interior design, #031017, or Blue Charcoal, evokes a sense of calm and sophistication. It can be used as an accent wall color in living rooms or bedrooms to create a cozy and enveloping atmosphere. Consider pairing it with lighter furniture and decor elements, such as cream-colored sofas or light wood accents, to balance the darkness and prevent the space from feeling too somber. The color works well in spaces that prioritize relaxation, such as home theaters or reading nooks. Accents in metallic colors such as gold or copper can add a layer of luxury and visual interest, creating a refined aesthetic.

For a balanced look, combine it with lighter and brighter colors, such as pastel shades or jewel tones. Accessorizing with metallic jewelry or colorful scarves can add visual interest and personality to an outfit featuring this color.
