Historically, ultramarine pigment was derived from lapis lazuli, making it a highly prized color.

The color #100299, a deep ultramarine, presents several accessibility considerations for web development. Its low luminance can pose challenges for users with visual impairments, especially when used as text color. According to WCAG guidelines, sufficient contrast between text and background is crucial. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #100299 for text, ensure it's paired with a light background to meet these contrast requirements. Tools like WebAIM's contrast checker can help verify compliance. Alternatively, consider using #100299 for larger graphical elements where contrast isn't as critical. Also, avoid using it as the sole indicator of interactive elements, as colorblind users might miss it. Supplement color cues with text labels or icons to ensure inclusivity.
