It is positioned closer to a vibrant azure than a muted navy. In the RGB color model, #313DE7 is composed of 19.22% red, 24.31% green, and 89.8% blue. This high concentration of blue gives the color its distinctive character. Cerulean blue is often associated with the sky and the ocean, symbolizing calmness, vastness, and inspiration.

The color #313DE7, a shade of cerulean blue, presents some accessibility challenges, especially in text-based applications. Its relatively low luminance of 19 means that text rendered in this color may lack sufficient contrast against lighter backgrounds, potentially making it difficult for users with visual impairments to read comfortably. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #313DE7 for text, it's crucial to pair it with very light colors, such as white or very pale yellow, to ensure readability. Additionally, avoid using this color for crucial interactive elements without providing clear visual cues and labels, as color alone should not be the sole indicator of functionality. For improved accessibility, consider using a slightly lighter or darker shade of blue or pairing it with high-contrast complementary colors in designs.
