General Information about #030299

The hex color #030299, also known as Ultramarine, is a deep shade of blue. In the RGB color model, it is composed of 1.18% red, 0.78% green, and 60% blue. This composition results in a color that is strongly biased towards the blue end of the spectrum. Ultramarine's association with royalty and art comes from its historical use in paints made from lapis lazuli. It is a color that is associated with stability, trust, and intelligence. Because it is such a dark color, it is best used as an accent color, especially for web design. The color is best used with white text because of its darkness.

The color #030299, a deep ultramarine, presents significant accessibility challenges, especially in web design. Its very low lightness value (perceived brightness) means it requires extremely light text (ideally white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. When using #030299 as a background, careful consideration is needed to meet these standards. Tools like contrast checkers can help verify compliance. Using it for small text is not recommended. Also, it's important to remember that color perception varies among individuals; testing with users, particularly those with visual impairments, is highly advisable to confirm the design's accessibility. Ensure interactive elements using this color provide sufficient visual cues beyond color alone.
