#170497

General Information about #170497

The hexadecimal color code #170497 represents a deep shade of ultramarine, a color traditionally associated with royalty, depth, and intellect. In the RGB color model, it is composed of 9.02% red, 1.57% green, and 59.22% blue. This substantial proportion of blue gives the color its characteristic intense hue. Ultramarine's name originates from the Latin 'ultramarinus', literally meaning 'beyond the sea', as the pigment was originally imported from Asia. Chemically, it is a complex sodium aluminosilicate with sulfur. It is a popular color choice for designers seeking to convey sophistication, mystery, and a sense of the unknown. However, its darkness requires careful consideration for contrast in design applications.

The color #170497, a deep ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 2% results in very poor contrast against typical light backgrounds like white or light gray. This can make text and UI elements difficult or impossible to read for individuals with low vision or color blindness. To ensure accessibility, it's crucial to use #170497 sparingly for text or interactive elements. When it is used, a very light background color is required to meet WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Consider pairing it with colors from a carefully chosen palette to provide sufficient visual distinction. Avoid using it alongside similar dark colors, as this will further reduce readability. Implementing text shadows or borders may improve legibility, but thorough testing with accessibility tools and users is essential to validate effectiveness.
