General Information about #000B10

The color #000B10, also known as Blue Charcoal, is a very dark shade of blue that borders on black. It belongs to the blue color family but has extremely low saturation and brightness, making it appear almost achromatic. In the RGB color model, it consists of 0 red, 11 green, and 16 blue. This hexadecimal code translates to a color that is more subdued and less vibrant than typical blues. Its darkness is due to the minimal presence of light, making it ideal for creating a sense of depth, mystery, or sophistication. The color is often associated with elegance, power, and the night sky. It is also frequently used in contexts where a neutral yet refined tone is desired. It is worth noting that such dark colors might pose legibility issues if not paired with sufficiently light foreground elements.

The hex color #000b10, also known as Blue Charcoal, presents some accessibility challenges, especially regarding text and interactive elements. Its low luminance value of approximately 0.004 makes it difficult to achieve sufficient contrast with lighter colors. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #000b10 as a background, ensure that the foreground text is a very light color, such as white (#FFFFFF), to meet these contrast requirements. Tools like contrast checkers can help verify compliance. Careful consideration is necessary to ensure readability and usability for individuals with visual impairments. Additionally, avoid using this color for elements that rely solely on color to convey information, as this could exclude users with color vision deficiencies. Providing alternative cues, such as text labels or icons, can help improve accessibility.
