This color is a very dark, saturated blue that tends towards the cooler end of the spectrum. Ultramarine has historically been a prized pigment, derived from lapis lazuli, and associated with royalty and religious art due to its rarity and vibrant hue. Modern ultramarine is synthetically produced, making it more accessible while retaining its characteristic depth and intensity. The color is often associated with feelings of trust, intelligence, and authority, making it suitable for various applications where these qualities are desired.

The color #04019A, a deep ultramarine, presents significant accessibility challenges, particularly in text applications. Its extremely low luminance value (very close to black) necessitates careful consideration of contrast ratios. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, especially for users with visual impairments. When using #04019A as a background, ensure that text is a very light color, ideally white (#FFFFFF), to achieve a contrast ratio above the minimum threshold of 4.5:1 for normal text and 3:1 for large text. Conversely, using #04019A as text on a light background is strongly discouraged due to its poor visibility. Alternative color combinations should be explored if high accessibility is a priority. Tools like contrast checkers can help verify compliance with accessibility standards. Consider also the psychological impact; very dark blues can sometimes be perceived negatively, so balance is key.
