General Information about #000033

The hex color #000033, also known as Black Rock, is a very dark shade of blue, almost appearing black to the untrained eye. It is composed of 0% red, 0% green, and 20% blue. In the RGB color model, it has values of R:0, G:0, B:51. This color's darkness means it has a very low luminance value. Colors like this are often associated with sophistication, mystery, and depth. Its subtle blue undertone can add a touch of elegance and refinement. In various design contexts, this color can be used to create a sense of drama or to provide a grounding element. However, due to its darkness, careful consideration must be given to its use, particularly regarding contrast and accessibility, to ensure readability and visual clarity.

The hex color #000033, also known as Black Rock, presents significant accessibility challenges, especially when used for text or interactive elements. Due to its very dark nature, it offers extremely low contrast against typical light backgrounds, making it difficult for users, particularly those with visual impairments, to perceive content effectively. To ensure inclusivity, it is crucial to pair this color with significantly lighter hues that provide a high contrast ratio, ideally exceeding the WCAG (Web Content Accessibility Guidelines) minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text and user interface components. Thorough testing with accessibility evaluation tools and real users is essential to validate the color combination's usability and readability. Avoid using this color for critical information or calls to action unless paired with appropriate contrast.
