General Information about #010533

The hex color #010533, also known as Black Rock, is an extremely dark shade of blue, almost appearing black. It belongs to the blue color family but has very low luminance. In the RGB color model, it is composed of 0.4% red, 2% green, and 20% blue. In the CMYK color model, it consists of 98% cyan, 90% magenta, 0% yellow, and 80% black. This color is often associated with sophistication, mystery, and depth. Its high concentration of blue gives it a cool and calming undertone, despite its darkness. It is used in graphic design, web design, and other creative fields to evoke a sense of elegance and formality. Due to it being so dark, the color is normally used in combination with much lighter colors.

The hex color #010533, also known as Black Rock, presents significant accessibility challenges, especially in web design. Its extremely low luminance makes it difficult to read text or distinguish elements against it. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against a background. Black Rock is highly unlikely to meet these ratios when paired with most foreground colors, including lighter shades. Therefore, if using this color, careful consideration should be given to the choice of foreground elements. It's crucial to pair it with significantly lighter colors to ensure readability for users with visual impairments. Designers must use color contrast checkers during the design process. Implementing features such as adjustable text sizes and allowing users to select alternative color schemes can further enhance accessibility when this dark hue is necessary for branding or design purposes.
