Due to its deep saturation, it is best used as an accent color rather than a primary background or foreground color, especially in digital applications. Its rich tone evokes feelings of calm and stability, often used to represent trust and authority. The color's historical significance in art adds to its appeal and timelessness.

The hex color #170494, also known as Ultramarine, presents significant accessibility challenges, particularly in text-based contexts. Its very dark hue results in low contrast against typical light backgrounds, such as white or light gray. This low contrast makes it difficult for individuals with visual impairments, including those with low vision or color blindness, to discern text rendered in this color. To ensure accessibility, it is crucial to pair #170494 with a very light color for text or interactive elements. Web Content Accessibility Guidelines (WCAG) recommend specific contrast ratios for different text sizes to meet Level AA and Level AAA compliance. Tools like contrast checkers can assess the color combination's compliance. Using #170494 for large graphical elements or as a background color might be acceptable, but careful consideration should be given to foreground elements to maintain readability and usability for all users. It's always beneficial to test color combinations with a diverse group of users, including those with visual impairments, to validate accessibility.
