In color psychology, blues like Sapphire are often linked to calmness, serenity, and reliability.

Its versatility also makes it suitable for a range of applications, from corporate logos to background elements, depending on the desired aesthetic.

The color #313E99, also known as Sapphire, presents some accessibility challenges, especially when used as a foreground color on a white or light background. Its relatively low luminance value means it may not provide sufficient contrast for users with visual impairments, making text difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Sapphire might fall short of these recommendations in many scenarios. To improve accessibility, consider pairing it with lighter shades of yellow, white, or other high-luminance colors to ensure sufficient contrast. Also, avoid using it for critical interactive elements without careful consideration of its contrast ratio against the background. Tools like contrast checkers can help evaluate the color's suitability for different uses.
