The color #155B83, also known as Blumine, is a dark shade of blue that evokes feelings of calmness, stability, and professionalism. It belongs to the blue color family and is often associated with trust, security, and authority. In terms of color theory, it can be described as a tertiary color, resulting from mixing a primary color (blue) with a secondary color (green or violet) and then muting it. The hexadecimal color code #155B83 breaks down as follows: the red component is 15 (9.4%), the green component is 5B (35.7%), and the blue component is 83 (51.4%). It is more saturated in blue than in red or green. Colors with the hex code starting with a single digit represent darker colours than the hex code of 6 digits starting with FF.

The color #155B83, also known as Blumine, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low lightness value (around 30%) means it requires careful consideration when used for text or interactive elements. According to WCAG guidelines, it's crucial to ensure sufficient contrast between text and background colors to meet minimum accessibility standards (AA level). For normal text (14pt/18px and larger), a contrast ratio of at least 4.5:1 is recommended, while for large text (18pt/24px and larger bold or 14pt/18px bold), a ratio of 3:1 is sufficient. When using #155B83 as a background, lighter text colors should be chosen, and vice versa. Tools like contrast checkers can accurately measure the contrast ratio. Also, don't rely solely on color to convey meaning as a supplementary visual cue is required, and consider providing alternative text descriptions for images or interactive elements using this color.
