General Information about Blue Charcoal

The hex color #010A13, also known as Blue Charcoal, is a very dark shade of blue with subtle cool undertones. It's composed of 0.4% red, 3.92% green, and 7.45% blue. In the RGB color space, it closely approaches black, contributing to its muted and reserved character. The color evokes a sense of depth and sophistication, often associated with elegance and modernity. It's commonly used in designs where a subtle, understated tone is desired, and is often chosen when aiming for a professional or minimalist aesthetic. Its subdued nature makes it a versatile choice that can be combined effectively with brighter hues to create contrast and visual interest, or with other dark tones for a more subdued, monochromatic palette.

The color #010A13, also known as Blue Charcoal, presents significant accessibility challenges due to its very dark nature. Its low luminance results in poor contrast against common background colors like white, making it difficult for users with visual impairments to read text or distinguish elements. To improve accessibility, it is crucial to pair this color with much lighter shades for foreground elements. Adhering to WCAG guidelines for contrast ratios is essential; aim for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Consider providing alternative color schemes that offer better contrast for users with different visual needs. Tools are available to check color contrast ratios and ensure compliance with accessibility standards.
