#140229

General Information about Black Rock

The hex color #140229, often referred to as "Black Rock", is a very dark shade of purple that leans heavily towards black. It belongs to the family of dark purples and its RGB (Red, Green, Blue) values are R:20, G:2, B:41. In the CMYK (Cyan, Magenta, Yellow, Key/Black) color model, its composition is approximately C:51%, M:95%, Y:0%, K:84%. This indicates that the color is primarily composed of cyan and magenta, with a significant amount of black added to darken it. Due to its high black component, #140229 exhibits low luminance and saturation, contributing to its muted and somber appearance. The color is not commonly found in nature but it resembles the color of dark rocks, such as obsidian.

The color #140229, also known as Black Rock, presents significant accessibility challenges due to its extremely low luminance. Its contrast ratio against white (#FFFFFF) is very poor, making text or user interface elements rendered in this color difficult to read for users with normal vision. For users with low vision or color blindness, the legibility issues are further exacerbated. To ensure accessibility, it's crucial to avoid using #140229 for text or important graphical elements against light backgrounds. When this color is unavoidable, providing sufficient contrast through the use of lighter foreground colors or employing techniques such as text shadows or outlines is necessary. WCAG guidelines recommend a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text against its background to meet Level AA compliance. Black Rock falls far short of these recommendations, making careful consideration and implementation of accessibility enhancements essential for inclusive design.
