General Information about Ultramarine (#011297)

In the RGB color model, it is represented as (1, 18, 151). Ultramarine's origins trace back to the semi-precious stone lapis lazuli, from which the pigment was originally derived. Its rich and vibrant hue made it highly valued in art, particularly during the Renaissance period.

This color is often associated with qualities such as trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven. It is frequently used in corporate branding and design to convey a sense of stability and reliability. Its striking depth also makes it a popular choice for creating dramatic and eye-catching visual effects.

The color #011297, a deep ultramarine, presents significant accessibility challenges, especially when used as a text color. Its low luminance value (very dark) requires careful consideration of contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #011297 for text, it's imperative to pair it with a very light background color to meet these contrast requirements. Otherwise, users with low vision or color blindness may struggle to distinguish the text from the background. Additionally, avoid using this color for crucial interactive elements or important information without providing sufficient contrast, as this could exclude users. Providing alternative styling options or high-contrast themes can further improve accessibility for a broader range of users.
