General Information about Black Rock (#020732)

The color #020732, also known as Black Rock, is a very dark shade of blue, almost appearing black to the naked eye. It belongs to the blue color family, specifically within the range of very low saturation and low luminance. In the RGB color model, it consists of 0.78% red, 2.75% green, and 20% blue. Its primary characteristic is its depth and subtlety, making it suitable for applications where a muted, sophisticated color palette is desired. This hex code is primarily used in digital design, web development, and graphic design to represent this specific dark blue hue. This color can be perceived differently based on the ambient light.

The hex color #020732, a very dark shade of blue, presents significant accessibility challenges, especially in text-based contexts. Due to its extremely low luminance, it provides insufficient contrast against commonly used background colors like white. This can make content difficult or impossible to read for users with visual impairments, including those with low vision, color blindness, or cataracts. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability. Black Rock falls far short of these requirements when paired with light backgrounds. Web developers should avoid using this color for text or important UI elements unless paired with a very light color to meet the contrast ratios. Using lighter hues such as #ADD8E6 for text on #020732 backgrounds would improve visibility.
