General Information about #0A1803

#0A1803, also known as Black Forest, is a very dark shade of green, almost appearing black to the untrained eye. It evokes feelings of nature, depth, and mystery, reminiscent of dense forests and hidden landscapes. This hex color has a very low luminance value, making it a challenging color to use effectively in design. In the RGB color model, it consists of 3.92% red, 9.41% green, and 1.18% blue. In the CMYK color model, it is composed of 58% cyan, 0% magenta, 87% yellow, and 91% black. The color's darkness stems from the high percentage of black ink needed to produce it, and is often associated with sophistication. Due to its low brightness, #0A1803 demands careful consideration when used in design to ensure sufficient contrast and accessibility, so it can be more legible and available to a broader audience.

The hex color #0A1803, also known as Black Forest, presents significant accessibility challenges, particularly in web design. Its extremely low luminance makes it difficult to perceive, especially for individuals with visual impairments or color blindness. Using this color as a primary text or background color without careful consideration of contrast ratios can render content illegible. According to WCAG guidelines, sufficient contrast between text and background is crucial for accessibility. To ensure readability, it's essential to pair #0A1803 with a much lighter color that provides a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, providing alternative text descriptions for any images or graphical elements using this color is vital. Avoid using #0A1803 for critical interactive elements like buttons or links unless a clear visual indicator, such as a contrasting border or text label, is present. Thoroughly testing your designs with accessibility tools and real users is highly recommended to identify and address any potential usability issues arising from the use of this dark color.
