General Information about #0101C9

The hexadecimal color code #0101C9 represents a very dark shade of blue. It is composed of 0.4% red, 0.4% green, and 78.8% blue. In the RGB color model, it is defined as (1, 1, 201). This color is frequently described as a dark blue, although some may perceive it as an indigo or ultramarine-like hue due to its high blue component. This color has a very low saturation, which makes it appear muted and deep. Because of the low red and green components and the high blue component, the color leans heavily towards the blue end of the spectrum. It is commonly used to convey a sense of calmness, authority, or sophistication, but its darkness requires careful consideration of contrast when used in design.

The color #0101C9, a very dark blue, presents significant accessibility challenges. Its extremely low luminance makes it difficult to see against most backgrounds, especially white. The contrast ratio is far below the WCAG recommended minimum of 4.5:1 for normal text and 3:1 for large text. Using this color for text or important user interface elements without careful consideration of contrast will result in a poor user experience for individuals with visual impairments, including those with low vision or color blindness. To improve accessibility, pair this color with a very light color such as white or a pale yellow to increase the contrast ratio. Larger text sizes also help, but it's still crucial to test the contrast. Avoid using this color for critical information or interactive elements unless sufficient contrast is ensured. Consider providing alternative color schemes to cater to different user preferences and needs.
