General Information about Ultramarine

In the RGB color model, it consists of 9.8% red, 4.3% green, and 55.3% blue. The color is often associated with royalty, wisdom, and spirituality. It has been historically valued as a pigment in paintings, particularly during the Renaissance. Ultramarine is a versatile color that can evoke feelings of calmness, authority, and sophistication. Its deep and complex tone makes it a popular choice for designers seeking to create a sense of depth and intrigue.

The color #190B8D, Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in low contrast against light backgrounds, making text and interface elements difficult to read. According to WCAG guidelines, sufficient contrast ratios are essential for ensuring readability. Ultramarine requires careful consideration of foreground colors to meet these standards. White or very light shades of yellow or green are necessary to achieve acceptable contrast. Additionally, relying solely on color to convey information should be avoided. Providing alternative cues such as text labels or icons is crucial for users who cannot distinguish between colors. Designers should use contrast checking tools to verify compliance with accessibility guidelines when using Ultramarine in their designs. Thoughtful application of this color can enhance user experience, but overlooking accessibility can lead to exclusion and frustration.
