#1803B0

General Information about #1803B0

The hex color #1803B0, often perceived as a dark blue, is a specific point within the RGB color spectrum. In the RGB color model, used in digital displays, this color is defined by its low red (18), nearly absent green (3), and high blue (176) components. Its perceived darkness stems from the low overall values of the red, green, and blue components. This color leans towards the cooler side of the spectrum, evoking feelings of calmness, stability, and trust. In color psychology, blues are often associated with professionalism and authority. The precise hue is created by fine-tuning the intensity of each of the three primary colors, creating a unique and identifiable shade.

The hex color #1803b0, a deep, dark blue, presents significant accessibility challenges, particularly in text applications. Its low lightness value results in very poor contrast against common background colors like white. According to WCAG guidelines, sufficient contrast is crucial for readability and usability, especially for users with visual impairments. To ensure accessibility, it is strongly recommended to avoid using #1803b0 for text on light backgrounds. If this color is essential to the design, consider using it sparingly and in larger font sizes, or pair it with very light or even white text. Alternatively, use it for decorative elements rather than crucial information. The contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text against its background. Using color contrast checkers is crucial to verify compliance and ensure inclusivity.
