General Information about Catalina Blue

Catalina Blue, represented by the hexadecimal code #182D7F, is a dark shade of blue that evokes feelings of depth, stability, and trustworthiness. It belongs to the blue color family, which is often associated with calmness, serenity, and intellect. This particular shade of blue is characterized by its high blue component and relatively low red and green components. In color theory, Catalina Blue can be described as a tertiary color, resulting from the mixing of a primary color (blue) and a secondary color (in this case, a very muted violet). Its hexadecimal representation indicates the specific proportions of red, green, and blue light that combine to produce this unique color. The color is named after Catalina Island in California, perhaps suggesting the deep blue color of the ocean surrounding the island.

The color #182D7F, also known as Catalina Blue, presents some accessibility challenges. Its dark hue results in a low contrast ratio against lighter backgrounds, potentially making text or interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for readability. To improve accessibility, consider pairing Catalina Blue with very light colors such as white (#FFFFFF) or light yellows (#FFFFE0) to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Avoid using it with similar dark colors as this will create insufficient contrast. Also, provide alternative cues like icons or labels in addition to color to convey information, ensuring usability for colorblind users. Proper implementation of ARIA attributes can further enhance accessibility by providing semantic information to assistive technologies.
