The color #150F8B, a deep ultramarine, presents some accessibility challenges. Its low lightness value (approximately 6%) results in a poor contrast ratio against standard white backgrounds. This can make text or fine details difficult to read for users with visual impairments. To improve accessibility, it's crucial to use a light-colored text or background. Consider pairings with shades of yellow, white or light greys to achieve sufficient contrast. Tools like contrast checkers can help ensure WCAG compliance, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Also consider using a larger font size or weight when this color is used for text to increase legibility.
