About Ultramarine (#130A8E)

The hexadecimal color code #130A8E represents a deep shade of ultramarine blue. It is composed of 7.45% red, 3.92% green, and 55.69% blue. In the RGB color model, this translates to R:19, G:10, B:142. This color is generally perceived as cool, calming, and sophisticated, and is often associated with trust, intelligence, and stability. Due to the low red and green values, the color leans heavily towards the blue spectrum. This particular shade of ultramarine can be used to create a sense of depth and mystery, as it is a dark and somewhat intense color. It is a less common color in every day designs, because of it's accessibility issues. Its use should be paired with very light colors.

The color #130A8E, a deep ultramarine, presents significant accessibility challenges, particularly when used as text against a white or light-colored background. Its low luminance value (approximately 3.5%) results in a very low contrast ratio, failing WCAG (Web Content Accessibility Guidelines) AAA standards for text sizes smaller than 18pt or 14pt bold. To improve accessibility, consider pairing it with lighter hues that provide a sufficient contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. White or very light shades of yellow or green could potentially meet these requirements. Avoid using this color for crucial elements like links or buttons without careful consideration of the surrounding colors and their impact on users with visual impairments. Providing alternative high-contrast themes can also enhance usability for a wider audience.
