General Information about #00025D

The hexadecimal color code #00025D, also known as Gulf Blue, is a very dark shade of blue. In the RGB color model, it is composed of 0% red, 0.78% green, and 36.47% blue. This composition results in a color that is perceived as deep and somewhat mysterious. The color is often associated with feelings of depth, stability, and authority, though its darkness can also convey a sense of solemnity or seriousness. In terms of color theory, #00025D falls into the blue color family, which is generally considered a cool color. This particular shade is far from the cyan side of the spectrum and is closer to a navy tone, because of the higher concentration of blue pigment. The color is not often found in nature and is mostly used on industrial applications that want to evoke a sense of stability or formality.

The color #00025D, a very dark shade of blue, presents significant accessibility challenges, especially in web design. Its extremely low luminance creates a stark contrast issue when paired with other dark colors, making text or interactive elements nearly invisible to users. To ensure readability and usability, it is crucial to use #00025D primarily with very light colors such as white (#FFFFFF) or very light grays. Adhering to WCAG (Web Content Accessibility Guidelines) contrast ratio requirements is essential. For normal text (size 14 regular / 18 bold or above) a contrast ratio of at least 4.5:1 and for large text (size 18 regular / 24 bold or above) a contrast ratio of at least 3:1 is required. Furthermore, avoid using #00025D for essential visual cues without providing redundant cues, such as text labels or icons, to accommodate users with visual impairments. Careful consideration and testing are vital to making content accessible to everyone.
